Texte intégralMain group supramolecular chemistry is a rapidly expanding field that combines the tools of coordination chemistry with the unusual and frequently unexpected coordination preferences exhibited by the main group elements. Application of established supramolecular design principles to those elements provides access to novel structure types and the possibility of new functionality introduced by the rich chemistry of the main group. Chapter I is a general review of the field of main group supramolecular chemistry, focusing in particular on the aspects of coordination chemistry and rational design strategies that have been thus far used to prepare polynuclear "metal"-ligand assemblies. Chapter II is a discussion of work toward supramolecular assemblies based on the coordination preferences of lead(II), in particular focusing on the 2-mercaptoacetamide and arylthiolate functionalities to target four-coordinate and three-coordinate geometries, respectively. Several possible avenues for further pursuing this research are suggested, with designs for ligands that may provide a more fruitful approach to the coordination of lead(II). Chapter III deals with the preparation of As 2 L 3 assemblies based on flexible ligand scaffolds. These assemblies exhibit structural changes in response to temperature and solvent, which may provide some insight into the subtle shape requirements involved in supramolecular guest binding. Chapter IV continues this work with an examination of how ligand structure affects mechanical coupling of stereochemistry between metal centers when the chelate ring is completed by a secondary bonding interaction such as the As-π contact. Finally, Chapter V presents a crystallographic and synthetic study of the nature of the interaction between pnictogens and arene rings. This interaction is ubiquitous in the coordination chemistry performed in the Johnson laboratory; understanding the role these interactions play in determining the final structure of supramolecular assemblies is vital to the preparation of more complex structures. Chapter VI presents a set of conclusions and outlook for future work on lead(II) supramolecular assemblies and the dynamic assemblies prepared from flexible organic scaffolds. This dissertation contains previously published and coauthored material.

Texte intégralClickable pillar[5]arene building blocks have been used for the efficient grafting of peripheral subunits onto the macrocyclic core. New liquid-crystalline pillar[5]arene derivatives have been prepared by grafting either p-dodecyloxybenzoate groups or percec-type dendrons on the macrocyclic scaffold. On the other hand, pillar[5]arene derivatives bearing peripheral porphyrin subunits have been efficiently prepared from the clickable pillar[5]arene building block and Zn(II)-porphyrin derivatives bearing a terminal alkyne function. Owing to an intramolecular complexation of the peripheral Zn(II)-porphyrin moieties by 1,2,3-triazole subunits, an original dynamic conformational equilibrium leading to a folding of the molecules has been evidenced by variable temperature 1H NMR studies. Finally, a clickable [2]rotaxane scaffold incorporating a free-base porphyrin stopper has been prepared and functionalized with ten peripheral Zn(II)-porphyrin moieties to afford a sophisticated photoactive supramolecular device

Includes bibliographical references.
Chapter 1: The Intriguing Geometric and Electronic Structure of Arene-Bridged Diuranium Tetrakisamido Complexes The focus of this chapter is to characterize and contextualize the bridged arene complex (-toluene)U2(N[t-Bu]Ar)4 (lb2-gl-toluene, Ar = 3,5-C6H3Me2). To do so, lb2-g-toluene is compared extensively with the mononuclear complexes (THF)U(N[1Ad]Ar)3 (2a-THF, THF = tetrahydrofuran), JIU(N[t-Bu]Ar)3 (la-I), IU(N['Ad]Ar)3 (2a-I), and Me3SiNU(N[1Ad]Ar)3 (2a- NSiMe3). In order to understand the properties of a unique compound such as lb2-pg-toluene, the rest of the series is based on classical uranium amide compounds. The syntheses, structures (X-ray crystal structures and solution behavior based on variable temperature, VT, NMR data), spectroscopic (X-ray absorption near-edge structure, XANES, and electronic absorption - UV- vis-NIR) and magnetic properties are discussed and interpreted with reference to results of density functional theory (DFT) calculations performed on model compounds. Reactivity studies of lb2-p-toluene are then presented and analyzed. Chapter 2: Arene Bridged Diuranium Complexes Supported by a Ketimide Ligand: Even and Odd Electron Redox Pairs The ketimide ligand NC[t-Bu]Mes (Mes = 2,4,6-C6H2Me3) employed in the present study allows for retention of three supporting ligands per uranium, giving rise to a three-legged piano stool geometry, and it also allows for incorporation of potassium ions as tight ion pairs. The generality of such a ligand is well supported by the existence of the two types of compounds M2(g-arene)U2(NC[t-Bu]Mes)6 (M2-32-g-arene, M = Na, K) and K-32-pt-arene, when the arene is naphthalene, biphenyl, trans-stilbene, or p-terphenyl.
(cont.) When toluene or benzene is the bridging arene, only odd electron species are formed including symmetrical complexes, K21-32- -arene', and asymmetrical complexes, K(DME)-32-g1-arene' (arene' = benzene, toluene). The reactivity patterns observed for the bridging arene ketimide compounds are complicated by loss of an alkali metal ion (K2-32-jg-arene with PhSSPh) or by additional redox processes (K-32-gl-arene with PhNNPh), but interesting products have been isolated. By contrast, the reaction of K2-32-g-arene with 1,3,5,7-cyclooctatetraene appears to be straightforward leading to K-3-COT. Compound 32-I-COT obtained from reaction of K-3-COT with 3-I-DME is an interesting example of an inverted sandwich and can be referred to as "inverted uranocene". Chapter 3: Uranium 2,2'-Bipyridyl Complexes Supported by Amide and Ketimide Ligands The synthesis and characterization of (bipy)2U(N[t-Bu]Ar)2 (lb-(bipy)2, bipy = 2,2'-bipyridyl, Ar = 3,5-C6H3Me2), (bipy)U(N[1Ad]Ar)3 (2a-bipy), (bipy)2U(NC[t-Bu]Mes)3 (3-(bipy)2, Mes = 2,4,6-C6H2Me3), and IU(bipy)(NC[t-Bu]Mes)3 (3-I-bipy) are reported. X-ray crystallography indicates that bipy coordinates as a radical anion in lb-(bipy)2 and 2a-bipy, and as a neutral ligand in 3-I-bipy. In 3-(bipy)2, one of the ligands is best viewed as a radical anion, while the other as a neutral ligand. These results are supported by NMR spectroscopy results of exchange experiments with 4,4'-dimethyl-2,2'-bipyridyl (dmb) and optical spectroscopy. In all complexes uranium is assigned a +4 formal oxidation state.

Texte intégralENGLISH ABSTRACT: The use of chiral oxazoline directed lithiation provides a highly diastereoselective (up to >99% de) route to meta functionalised inherently chiral calixarenes. This methodology can be used on both the butylated and debutylated calixarene systems and is tolerant of a wide range of different electrophillic quenches allowing access to a structurally diverse range of inherently chiral metafunctionalised calixarenes. The oxazoline directing group can be removed via hydrolysis, generating a range of functionalised calixarene carboxylic acids in high ee. We also demonstrate that the use of derivative alkyllithiums such as cyclopentyl lithium can provide significantly enhanced diastereoselectivity over the conventional organolithiums such as sec-butyl lithium, when employed in ortholithiation reactions of this nature. The differences in diastereoselectivity associated with the different alkyllithiums can be tied, in certain cases, to the steric bulkiness associated with the individual reagents. In this regard we have found that the use of the so called Tolman angle or cone angle approach allows quantification of the relative steric bulk of the alkyllithium. We also detail that the oxazoline directing group provides a hitherto unknown ability to be diastereoselectively tuned through the choice of the ligand system in the ortholithiation reaction. In this regard the development of a series of diglyme based ligands have proved to provide a highly diastereoselective means of inverting the chirality from that which the use of the conventional TMEDA ligand is able to generate (up to –92% de). The use of diglyme ligands to invert the sense of chirality is also shown to occur on the ferrocenyloxazoline system and presents an apparently general and hitherto unknown facet of asymmetric oxazoline directed ortholithiation. This diglyme induced inversion has been shown to be controlled through a secondary nitrogen coordinated mechanism that is able to operate with chiral oxazolines.
AFRIKAANSE OPSOMMING: Die gebruik van chirale oksasoliengerigte litiëring verskaf ’n hoogs diastereoselektiewe (tot en met >99% do) roete om metagefunksionaliseerde, inherente chirale calixareen produkte te sintetiseer. Deur gebruik te maak van verskillende elektrofiele kan die metodologie toegepas word op beide gebutileerde en de-gebutileerde calixareen sisteme om ’n reeks uiteenlopende inherente chirale, meta-gefunksionaliseerde calixareen produkte te vorm. Die oksasolien groep kan daarna verwyder word deur hidroliese om ’n reeks gefunksionaliseerde calixareenkarboksielsure te vorm in baie hoë eo. Ons het ook gedemonstreer dat die gebruik van afgeleide alkiel-litiums, soos siklopentiel-litium, kan bydrae tot aansienlik verhoogde diastereoselektiwiteit as dit vergelyk word met meer algemene organolitiums soos sekbutiellitium, tydens ortolitiëring reaksies van hierdie natuur. Die verskille in diastereoselektiwiteit kan verbind word, in sekere gevalle, tot die steriese bonkigheid van die individuele reagense. Deur gebruik te maak van die sogenaamde Tolmanhoeke of die koniesehoek benadering is dit moontlik om die relatiewe steriese bonkighied van alkiellitiums te kwantifiseer. Daar was ook bepaal dat die oksasoliengroep die ongekende vermoë besit om die diastereoselektiwiteit van die produk te stem deur die keuse van verskillende ligand sisteme tydens die ortolitiëring reaksie. Daar was bepaal dat die chiralitiet van die produkte omgekeer kan word op ’n hoogs diastereoselektiewe manier, deur gebruik te maak van ’n reeks ontwikkelde diglymegebaseerde ligande, indien dit vergelyk word met die produkte wat deur die konvensionele TMEDA gegenereer was (tot en met –92% do). Die gebruik van diglyme ligande was ook getoets op ferroseenoksasolien sisteme en dit was bevind dat dieselfde omkering in chiraliteit ook plaasvind wat aanleiding kan gee tot 'n oënskynlik algemene en tot nou toe onbekende faset van asimmetriese oksasoliengerigte orto-litiëring. Dit is bepaal dat hierdie diglyme geïnduseerde omkering in chiraliteit beheer word deur middel van 'n sekondêre stikstofgekoördineerde meganisme, wat in staat is om saam te werk met chirale oksasoliene.

Texte intégralAnalogues of cyclotriveratrylenes and calix[n]arenes, pillar[n]arenes are composed of 1,4-disubstituted hydroquinone subunits linked by methylene bridges in their para positions. This macrocyclic core has been used as a compact scaffold for the preparation of nanomaterials. In this context, the chemical modification of the methylene bridge has been achieved to further functionalize the core in a way never explored so far. Firstly, oxidation of this position followed by Colvin reaction generated a strained triple bond in the macrocyclic scaffold. This particularity allowed the introduction of functional groups under copper free Huisgen 1,3-dipolar cycloadditions as well as by thermal [2+2] cycloadditions normally prohibited. Insertion of [60]fullerene on the methylene bridge has been also carried out. In a second time, photoactive [2]rotaxanes have been obtained from this fulleropillar[5]arene. Finally, a new methodology for the preparation of [2]rotaxanes has been developed. By exchange of activated stoppers, various [2]rotaxanes were thus obtained and this method is not limited by the nature of the stopper. This methodology has been used to prepare new liquid crystalline rotaxane derivatives by introduction of clickable stoppers followed by the grafting of dendritic mesogenic subunits
