Streszczenie:
Molecular Dynamics is a very powerful technique for the investigation of matter at nanoscopic level. However, it’s application in many fields, such as the investigation of many relevant processes of cell biology, is restricted by issues of computational cost. Therefore, in recent years, a growing interest has been generated by the introduction of Coarse-Grained (CG) models, that allow the investigation of bigger systems for longer timescales. In this thesis, Molecular Dynamics was used in order to gain a quantitative understanding of mechanical and di.usive processes of DNA molecules in solution, and in order to parametrise a Coarse Grained model of DNA capable of a qualitative description of the mechanical behaviour of the all-atom model at equilibrium. A software package for the computation of Coarse-Grained interaction force-fields, making use of the recently developed Multiscale Coarse-Grained Method (MSCG) by Izvekov and Voth [1] was implemented. We tested and validated the method by performing a one-point-per-molecule coarse graining of TIP3P water. The resulting model was able to reproduce the fluid structure (its radial distribution function) in a satisfactory and nearly quantitative way. Finally, we applied the MSCG method to a more demanding problem, namely the parametrisation of a 3-point-per-residue coarse-grained model of double-stranded DNA. As a consequence, the agreement of the obtained CG model with the atomistic structure was still not quantitative. In particular, the helical geometry was qualitatively preserved and the Root-Mean-Square Displacement (RMSD) of the coarse-grained model was stable over the trajectory, but higher than its all-atom counterpart. We suggest several possible routes for future improvements. In particular, the explicit modeling of torsional degrees of freedom of the DNA backbone, and the use of recently introduced methods for the refinement of the MSCG estimation of force-field parameters, and a more accurate treatment of Coulombic interactions.

Streszczenie:
Recent studies have demonstrated that nanoscale crystalline iron oxide minerals are common in natural systems. The discipline of nanoscience suggests that these particles in the size range of approximately 1-50 nm will have properties that deviate from the bulk properties of the same material and that these properties will change as a function of particle size. This study begins to fill the void of corresponding experimental investigations that apply the principles of nanoscience to the geochemical reactivity of nanominerals. The rate of Mn²⁺(aq) oxidation on hematite with average diameters of 7.3 nm and 37 nm was measured in the presence of O₂(aq). In the pH range of 7-8, the surface area normalized rate was one to two orders of magnitude greater on the 7.3 nm average diameter particles. Based on the application of electron transfer theory, it is hypothesized that the particles with diameters less than approximately 10 nm have surface crystal chemical environments which distort the symmetry of the MnMn²⁺ surface complex, reducing the energy required to reorganize the coordinated ligands after oxidation to Mn³⁺. Cu²⁺, an analog for Mn³⁺, was used to probe for the presence and nature of the proposed changes in surface structure. Cu²⁺ and Mn³⁺ show similar electronic structure changes in response to the surrounding crystal field due to their d-electron configurations and Jahn-Teller coordinative distortions. Batch sorption experiments on hematite nanoparticles revealed a shift in the pH-dependent adsorption of Cu²⁺(aq). Specifically, an affinity sequence of 7 nm > 25 nm = 88 nm was determined based on the shift of the 7 nm sorption edge to approximately 0.8 pH units lower than that for the 25 nm and 88 nm samples. These data support the hypothesis that unique binding sites exist on the 7 nm nanoparticles that are not significantly present on the larger particles. The National Nanotechnology Initiative stresses the need to address the broader societal impacts of nanoscale research. This dissertation embraces this viewpoint through the development and inclusion of "Nano2Earth: Introducing Nanotechnology Through Investigations of Groundwater," a curriculum which combines nanoscience with the Earth sciences for high school students.

Streszczenie:
Le sujet de cette thèse est l'observation de parois de domaines ferromagnétiques dans des nanofils cylindriques, ainsi que leur dynamique sous champs magnétiques appliqués. Ces nanostructures ont été électrodéposées par mes collègues dans des membranes d'alumine nanoporeuse servant de gabarits à géométrie adaptable. Les matériaux sont des alliages magnétiques doux de FeNi ou CoNi ; les diamètres vont de 150 nm à 250-300 nm, avec une longueur typique de 30 µm.Mon travail a d'abord englobé des développements instrumentaux de porte-échantillons et d'électronique haute fréquence visant au déplacement de parois sous champ. J'ai étudié cette dernière grâce au dichroïsme magnétique circulaire des rayons X couplé à la microscopie électronique de photoémission (XMCD-PEEM), en géométrie dite de transmission ou d'ombre. Cette technique synchrotron permet le suivi de la configuration interne de paroi avant et après déplacement ; en raison de la forte reproductibilité requise par le XMCD-PEEM résolu en temps, la dynamique en temps réel est pour le moment inaccessible.La réponse des parois de domaines ferromagnétiques à un champ magnétique est notoirement caractérisée par leur mobilité, c'est-à-dire le rapport de la vitesse atteinte sur le champ. Dans les nanofils cylindriques, un ingrédient nouveau apparaît dans le cas d'un type de paroi absent dans les bandes plates : la paroi à point de Bloch (Bloch point wall, BPW). Non seulement cette paroi comporte une singularité micromagnétique, c'est-à-dire un point où l'aimantation disparaît (le point de Bloch), mais elle possède également un degré de liberté discret représentant le sens d'enroulement d'aimantation autour de l'axe du fil. Il a été prédit que le déplacement de BPW sous champ suffisamment intense résulte en la sélection de l'un des deux seuls sens possibles. En d'autres termes, un des deux enroulements devient instable. Dans cette thèse, je rapporte l'observation expérimentale de cette sélection dans une majorité de déplacements de BPW.Il n'a pas été possible de mener des mesures de mobilité, néanmoins, mes expériences ont mis en évidence des transformations jusqu'ici non prévues en simulation entre types de parois. La BPW contenant un défaut topologique (le point de Bloch lui-même), ce comportement inattendu remet en question la protection topologique parfois attribuée aux textures topologiquement non-triviales. Bien que rappelant la conversion entre parois transverse et vortex dans les bandes, ces transformations dans les nanofils cylindriques impliquent des configurations micromagnétiques topologiquement non-équivalentes, par contraste avec les parois des bandes sus-mentionnées. De plus, la toute relative stabilité observée des types de parois suggère la prudence dans l'interprétation de future mesures de mobilité dans de tels systèmes dès lors que la configuration interne de paroi n'est pas résolue.En-dehors de tels échantillons électrodéposés, j'ai également étudié un nanofil cœur-coquille crû verticalement par des collègues. Cette nanostructure cylindrique créée par dépôt induit par faisceau d'électron focalisé (FEBID) possèdait un cœur nanocristallin de cobalt et une coquille de platine. Sa configuration magnétique a été également étudiée par XMCD-PEEM en transmission. Contrairement au fils précédemment mentionnés et posés sur leur substrat sur toute leur longueur, cet échantillon cœur-coquille était vertical et sans modulations de diamètre. En revanche, la géométrie coudée du fil a été conçue pour favoriser le piégeage de parois. Dans cette configuration innovante d'imagerie, le défi a été de remonter autant que possible à l'état magnétique du fil ; il m'a été possible de démontrer la présence d'au moins une paroi de domaine
The thesis is concerned with the observation of ferromagnetic domain walls in cylindrical nanowires, as well as their dynamics under applied magnetic fields. These nanostructures were electrodeposited by colleagues of mine into nanoporous alumina templates with a tailored pore geometry. The materials are soft FeNi or CoNi alloys; the diameters range from 150 nm to 250-300 nm, with a typical length of 30 µm.My work first comprised experimental developments of sample holders and high-frequency electronics towards field-induced domain wall motion. The latter I investigated with X-ray Magnetic Circular Dichroism coupled to transmission PhotoEmission Electron Microscopy (XMCD-PEEM). This synchrotron-based technique allows to monitor the internal domain wall configuration before and after displacement; due to the stringent requirements of time-resolved XMCD-PEEM experiments in terms of reproducibility, the real-time dynamics is out of reach as of yet.The response of ferromagnetic domain walls to applied magnetic fields is notably characterized by their mobility, i.e. the ratio of attained velocity to field strength. In cylindrical nanowires, a novel ingredient emerges in the case of one domain wall type that is absent in flat strips: the Bloch point domain wall. Not only does this domain wall host a micromagnetic singularity, that is to say a point where magnetization vanishes (the Bloch point), but it also possesses a discrete degree of freedom representing the sense of magnetization winding around the nanowire axis. It has been predicted that Bloch point wall motion under sufficiently high fields leads to this degree of freedom selecting one of its only two possible values. In other words, one winding becomes unstable. I report in this thesis experimental evidence of such a selection in a majority of Bloch point wall motion events.Although mobility measurements could not be carried out, my experiments have furthermore evidenced transformations between domain wall types that had not been predicted in simulations. Since the Bloch point wall contains a topological defect (the Bloch point itself), this unexpected behaviour questions the sometimes argued protection attributed to topologically non-trivial textures. While reminiscent of the well-known conversion between transverse and vortex walls in strips, these transformations in cylindrical nanowires involve topologically non-equivalent micromagnetic configurations, in contrast with the aforementioned transverse and vortex walls. Moreover, the observed only relative stability of domain wall types suggests caution in the interpretation of future mobility measurements in such systems, if the internal wall configuration cannot be resolved.Aside from such electrodeposited samples, I have also studied an upright core-shell nanowire grown by colleagues with Focused-Electron-Beam-Induced Deposition. This nanostructure featured a nanocrystalline cobalt core and a platinum shell. Its magnetic configuration was investigated with transmission XMCD-PEEM as well. Contrary to the aforementioned horizontally-lying wires, the core-shell sample was vertical with no diameter modulations. On the other hand, the geometry featured bends engineered to favour domain wall pinning. In this novel imaging configuration, the challenge was to recover as much of the nanowire's magnetic state as possible. I was able to demonstrate the presence of at least one domain wall

The reaction of HCl with clean, Cu(100) and (111), and Au/ Cu(100) surfaces was investigated using x-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) under ultra high vacuum (UHV) conditions. Exposure of the Cu(100) and (111) samples to HCl at room temperature leads to the formation of a saturated copper chloride monolayer. In the case of Cu(100), the saturated coverage was half monolayer corresponding to a c(2x2)-Cl reconstruction (half monolayer is 7.25x1014 cm-2) while for Cu(111) it was one third monolayer consistent with the reconstruction of (√3x√3)R30o (one third monolayer 5.9x1014 cm-2). The interaction of HCl with preoxidised Cu(100) and (111) showed different behaviour from those of clean copper surface depending on the way of interaction of oxygen with copper surface. Interaction of HCl with peroxidised Cu(111) at saturation oxygen coverage leads to the adsorption of chlorine on top of the copper surface with one third coverage. In contrast, presence of oxygen on Cu(100) surface at saturation coverage or less leads to adsorb chlorine but with an excess in chlorine concentration (more than the expected c(2x2) coverage). Oxidized Cu(100) and (111) surface at elevated temperature leads to the formation multi oxide layer. The two oxide surfaces („‟44‟‟ and „‟29‟‟) observed at the Cu(111) depend on the temperature of the substrate at the time of oxidation. The (√2x2√2)R45o structure was observed on the Cu(100) surface on heating which is the same structure formed at saturation coverage at room temperature. Interaction of HCl with Cu(100) and (111) surfaces covered by multilayers of oxide lead to adsorption of chlorine on top of the copper surface with a coverage more than more than the saturation coverage. Interaction of HCl with Au/Cu(100) showed two different behaviour depending on the gold coverage. Au/Cu(100) alloy formed at half monolayer of gold coverage, forming c(2x2) structure. Exposure of the Au/Cu(100) alloy at half monolayer of gold coverage to HCl leads to the formation of c(2x2)-Cl structure with saturation coverage of half monolayer in similar manner of interaction of HCl with the clean cu(100) surface. Interaction of HCl with Au/Cu(100) surface at gold coverage more than half monolayer leads to a dealloying of the gold from the copper surface and forming the Au(111) surface. Cu-Cl formed underneath the Au(111) surface with excess of chlorine concentration.

The study presented in this document is the result of three years of research into the complex world of Molecular Dynamics applied to biological cell membranes. The simulation of biological tissues involves not only an excellent knowledge of the numerical calculus and its related tools, but a profound comprehension of the biological and medical literature associated with the phenomenon. By the other hand, the use of high performance facilities is essential for the computation of the Molecular Dynamics models in order to obtain results in acceptable times, so the latest technological advances have played a decisive and important part in this eld of research. The presented obtained results about shock wave interaction with biological membranes, as well as the air ow through the alveolar surface, are part of a new line of research usually known as "virtual experimental". This name comes from the fact that any physical or chemical situation can be re-created into a computer system to calculate its propagation in time. The results of the interaction of shock waves with biological cell membranes have been particularly satisfactory and they have opened a new line of investigation into cancer research. A numerical proportional relation between the shock wave impulse and the value of lateral di usion (from 9.80 to 12.84 10 .7 cm2 s ), as well as the simulation of the transient provoked by the wave into a NPT ensemble are a successful achievement. Other computations of this type of interaction have been simulated into an NVE ensemble as well, however the obtained results for the lateral di usion, in the order of 10 .7 cm2 s , showed no trend regarding the shock wave and the transient e ect could not be simulated. On the other hand, the recreation of the air ow through the alveolar surface is an initial step into the solution of all the controversy surrounding this extremely complex system known as alveolar surface network. An alveolar membrane of around 7 nm has been successfully simulated in agreement with Scarpelli's experiments. This lipid-protein membrane model simulated can serve as a virtual experiment in order to solve the controversy about the alveolar surface. It points to the possibility of air ow through a stable two-layered DPPC phospholipid structure either from a numerical or physical and biological point of view and the existence of an alveolar membrane at the end of the bronchial tubes.

Chapter 1 includes a review on dendrimers, their synthesis and applications, with a particular focus on urea-linked dendritic species. The synthetic strategy utilised in this body of work was based on the preparation of a number of branched synthetic building blocks possessing differing terminal functionality. These branched dendrons, bearing three terminal residues and based on the cheap starting material tris(hydroxymethyl)aminomethane (TRIS) 23, involved the coupling of 3.3 equivalents of an appropriately para-substituted benzoic acid chloride with BOC protected TRIS 24 in DCM in the presence of triethylamine. The p-nitro, p-methoxy and p-methyl benzoyl chloride starting materials were obtained commercially, whilst N-(4-carboxyphenyl)maleimide was synthesised according to literature procedures. The BOC protected dendrons (25–27, 34) were synthesized in yields ranging from 50–92%. Deprotection of the BOC protected dendrons 25 and 26 in DCM with TFA, followed by the addition of 1M Na2CO3 afforded the TFA salts 35 and 36, respectively. The corresponding free base amines 37 and 38 were obtained on further treatment of the TFA salts with sodium carbonate. Deprotection of the BOC protected dendrons 27 and 34 afforded the free amines 39 and 48 directly after treatment with sodium carbonate. Synthesis of functionalised branched molecules containing 6- and 9-peripheral functionalities was achieved by refluxing 2 or 3 equivalents of the free amine dendrons with the bi- or tri- functional isocyanate cores, 15 and 45, in refluxing DCM, in most cases the products precipitated from the reaction mixture after 18 h and were isolated simply by filtration, otherwise the removal of the solvent from the reaction mixture afforded the spectroscopically pure product. Conversion of the peripheral nitro functionalised species 14 and 21 to the corresponding amines occurred smoothly via hydrogenation using 5% Pd/C under elevated temperature and pressure (DMF, 55 ºC, 600 psi) and afforded the polyamine 6-mer 51 in 92% yield and the 9-mer 50 in 90% yield, respectively. Similarly, conversion of the methoxy coated 9-mer 42, to the corresponding phenolic compound (AlBr3, dodecane thiol, DCM) afforded the 9-mer polyphenol 52 in an 87% yield. All compounds prepared were fully characterised and crystal structures were obtained for 26 and 35. Chapter 2 includes a review on self-assembled monolayers of organosulfur compounds on gold, applications, patterning techniques and techniques for the characterisation of these surfaces. A number of surface monomers were successfully synthesized, to be used for various surface functionalisations, including the formation of an amine reactive N-hydroxysuccinimide (NHS) disulfide 53, via the DCC coupling of 11,11’-dithiobisundecanoic acid 54 with N-hydroxysuccinimide with an isolated yield of 30%. A novel protein-resistant monomer 58 was also synthesized from 11-undecanoic acid 55 via an acid chloride coupling with triethylene glycol monomethyl ether 58, and isolated in a 72% yield. A number of attempts were made to produce an acyl azide SAM monomer 59, with success finally achieved via the acid chloride coupling of 11,11’-dithiobisundecanoic acid 54 with 5-amino-1,3-benzenedicarbonyl diazide 62 to produce 59 with an isolated yield of ~ 30%. Gold surfaces were prepared on atomically flat silicon wafers using an argon-ion sputterer. SAM films were formed on the gold surfaces via traditional solution based self-assembly methodology. A UV patterning protocol was developed, and a successful patterning trial using the NHS terminated monomer to backfill the UV exposed areas of a dodecane thiol monolayer was achieved and visualized using AFM and fluorescence microscopy after treating the surface with aminofluorescein. The covalent attachment of green fluorescent protein to the monolayer surface via reaction with the NHS terminated monolayer was demonstrated. The fluorescence of the biomolecule was preserved. The formation of a monolayer using the acyl azide monomer 59, was characterised by contact angle and XPS analysis. However, preliminary studies into the activation of the acyl azide surface into the reactive isocyanate were unsuccessful. There is however, significant scope for further investigations into this interesting surface technology. Chapter 3 includes a review on heterobifunctional linker technology with a particular focus on amine and thiol reactive moieties and literature examples of heterobifunctional linkers of this type. Synthesis of heterobifunctional reagents such as 71 and 74 via a two step synthetic methodology involving the coupling of maleic anhydride with the parent amino-acids in acetic acid, followed by a one pot cyclisation and NHS esterification using DCC in DMF were successful, with overall yields of 9% and 32% respectively for the two reaction steps. The one pot extension of 74 with 6-aminohexanoic acid, followed by DCC, facilitated NHS esterification was achieved successfully in a yield of 30%. Attempts to extend 74 with the synthesised amino acid 88 were unsuccessful due to the insolubility of 88 in organic solvents. A different synthetic strategy was devised towards the synthesis of 85 with the coupling of 74 and mono BOC protected ethylene diamine 91 in DCM to give 93 in an isolated yield of 60%. Deprotection of the terminal amine was achieved via reaction with TFA in DCM however all attempts to prepare the free amine were unsuccessful. Subsequent attempts to couple 94 with both succinic anhydride and 92 were unsuccessful. A maleimide functionalized crown ether was synthesised as a molecule for protein modification via the reaction of 74 with 4’-aminobenzo-15-crown-5 97 to produce 98 in an 80% yield. All compounds were fully characterised with crystal structures obtained for 74, 79 and 89.

Streszczenie:
An important new area of science and engineering relates to nanoscience and nanotechnology, which has been defined as “the emerging capability of human beings to observe and organise matter at the atomic level”. The purpose of this study is to examine a technology enabled learning approach that is informed by perspectives from an embodiment framework of cognition. The study aimed to enhance students’ understanding of challenging nanoscience concepts at the undergraduate level, such as surface area to volume relationships and size dependent properties. Students learned the targeted nanoscience knowledge using two different learning technologies: (a) the experimental group with Agent-Based Models (ABMs) and (b) the comparison group with dynamic visualisations. An empirical study was conducted to compare students in these two groups in terms of learning outcomes and reasoning strategies on assessments of declarative and procedural knowledge as well as solving transfer problems. Given earlier research that proposed ABMs provide an embodied approach for learning, three indicators based on an embodiment framework of cognition were used to compare these two learning approaches: (a) perspective taking, (b) causal inference making, and (c) reasoning strategies. The results of this study revealed no significant differences on declarative knowledge gains between the two groups; however, the ABM group significantly outperformed the dynamic visualisation group on the procedural knowledge and knowledge transfer assessments. Moreover, analyses of the post-test think-aloud video protocols revealed that the majority of the ABM students used first- to third-person perspectives, made causal inferences, and spontaneously used gestures, whereas students in the dynamic visualisation group did not. These results suggest that the ABM students were employing sensorimotor processes and mental simulations associated with an embodiment framework of cognition as they generated their solutions to these problems, while the dynamic visualisation students seemed to rely on memory retrieval of information from the videos. Overall, the findings of this study demonstrate that using ABMs to learn nanoscience phenomena can be more effective than learning with dynamic visualisations. In addition to the superior learning outcomes, students using the ABM approach demonstrated thinking and gestural behaviours that are consistent with an embodied framework of cognition. Given the extensive use of dynamic visualisations in science teaching, further research is needed to determine if ABMs might provide a superior approach for helping students to learn challenging scientific knowledge in nanoscience and other areas. Finally, it is hoped this study might stimulate further interest in research areas the nature of innovative learning experiences for understanding difficult scientific knowledge and their underlying theoretical mechanisms.

Synthesis of functionalised branched molecules containing 6- and 9-peripheral functionalities was achieved by refluxing 2 or 3 equivalents of the free amine dendrons with the bi- or tri- functional isocyanate cores, 15 and 45, in refluxing DCM, in most cases the products precipitated from the reaction mixture after 18 h and were isolated simply by filtration, otherwise the removal of the solvent from the reaction mixture afforded the spectroscopically pure product. Conversion of the peripheral nitro functionalised species 14 and 21 to the corresponding amines occurred smoothly via hydrogenation using 5% Pd/C under elevated temperature and pressure (DMF, 55 ºC, 600 psi) and afforded the polyamine 6-mer 51 in 92% yield and the 9-mer 50 in 90% yield, respectively. Similarly, conversion of the methoxy coated 9-mer 42, to the corresponding phenolic compound (AlBr3, dodecane thiol, DCM) afforded the 9-mer polyphenol 52 in an 87% yield. All compounds prepared were fully characterised and crystal structures were obtained for 26 and 35. Chapter 2 includes a review on self-assembled monolayers of organosulfur compounds on gold, applications, patterning techniques and techniques for the characterisation of these surfaces. A number of surface monomers were successfully synthesized, to be used for various surface functionalisations, including the formation of an amine reactive N-hydroxysuccinimide (NHS) disulfide 53, via the DCC coupling of 11,11’-dithiobisundecanoic acid 54 with N-hydroxysuccinimide with an isolated yield of 30%. A novel protein-resistant monomer 58 was also synthesized from 11-undecanoic acid 55 via an acid chloride coupling with triethylene glycol monomethyl ether 58, and isolated in a 72% yield. A number of attempts were made to produce an acyl azide SAM monomer 59, with success finally achieved via the acid chloride coupling of 11,11’-dithiobisundecanoic acid 54 with 5-amino-1,3-benzenedicarbonyl diazide 62 to produce 59 with an isolated yield of ~ 30%. Gold surfaces were prepared on atomically flat silicon wafers using an argon-ion sputterer. SAM films were formed on the gold surfaces via traditional solution based self-assembly methodology. A UV patterning protocol was developed, and a successful patterning trial using the NHS terminated monomer to backfill the UV exposed areas of a dodecane thiol monolayer was achieved and visualized using AFM and fluorescence microscopy after treating the surface with aminofluorescein. The covalent attachment of green fluorescent protein to the monolayer surface via reaction with the NHS terminated monolayer was demonstrated. The fluorescence of the biomolecule was preserved. The formation of a monolayer using the acyl azide monomer 59, was characterised by contact angle and XPS analysis. However, preliminary studies into the activation of the acyl azide surface into the reactive isocyanate were unsuccessful. There is however, significant scope for further investigations into this interesting surface technology. Chapter 3 includes a review on heterobifunctional linker technology with a particular focus on amine and thiol reactive moieties and literature examples of heterobifunctional linkers of this type. Synthesis of heterobifunctional reagents such as 71 and 74 via a two step synthetic methodology involving the coupling of maleic anhydride with the parent amino-acids in acetic acid, followed by a one pot cyclisation and NHS esterification using DCC in DMF were successful, with overall yields of 9% and 32% respectively for the two reaction steps. The one pot extension of 74 with 6-aminohexanoic acid, followed by DCC, facilitated NHS esterification was achieved successfully in a yield of 30%. Attempts to extend 74 with the synthesised amino acid 88 were unsuccessful due to the insolubility of 88 in organic solvents. A different synthetic strategy was devised towards the synthesis of 85 with the coupling of 74 and mono BOC protected ethylene diamine 91 in DCM to give 93 in an isolated yield of 60%. Deprotection of the terminal amine was achieved via reaction with TFA in DCM however all attempts to prepare the free amine were unsuccessful. Subsequent attempts to couple 94 with both succinic anhydride and 92 were unsuccessful. A maleimide functionalized crown ether was synthesised as a molecule for protein modification via the reaction of 74 with 4’-aminobenzo-15-crown-5 97 to produce 98 in an 80% yield. All compounds were fully characterised with crystal structures obtained for 74, 79 and 89.
