Abstract (sommario):

This thesis work reports developments in the coordination chemistry of ruthenium porphyrin complexes, both in terms of the synthesis and chemistry of new compounds, as well as the study of the solution chemistry of some previously reported complexes. The synthesis, characterization and chemistry of ten new Ru(porp) coordination complexes in the oxidation states Ru[superscript]Ⅲ and Ru[superscript]Ⅳ containing halide (Br, CI) and other axial ligands (pyridine, CH₃CN, NH₃ and SbF₆) are described in this thesis. Some additional ten Ru(porp) complexes have been studied in situ. Measurement of the rate constants for forward and reverse reactions and the corresponding equilibrium constant by 'H NMR and UV/visible spectroscopy for the dissociation of PPh₃ ligand from Ru(OEP)L(PPh₃) (OEP is the octaethylporphyrinato dianion; L = CO, PPh₃) in C₇D₈ to generate the previously reported five-coordinate Ru(OEP)L complexes allowed for an estimation of the Ru-P bond strength (64 ± 9 kJ mol⁻¹) in these complexes. A study of PPh₃ dissociation from Ru(OEP)CO(PPh₃) in C₇D₈ and in CDC1₃ indicates that solvation effects play a major role, with CDC1₃ being more capable than C₇D₈ of solvating the Ru(OEP)CO complex. The presence of trace H₂0 in these systems was a major problem, and the coordination of H₂0 to Ru(OEP)L complexes to generate the in situ Ru(OEP)L(H₂0) complexes (L = CO, PPh₃) is described. The formation of Ru(OEP)L(H₂0) and the observed difference in the solvation of Ru(OEP)CO by C₇H₈ and CHC1₃ indicate that truly Five-coordinate species may not exist in solution. The outer-sphere oxidation of Ru [superscript]Ⅳ(OEP)PPh₃ by 0₂ to give [Ru [superscript]Ⅳ(OEP)OH]₂0 was shown to occur only in the presence of H₂0. Mechanistic studies on the previously reported reaction of HCI with [Ru(OEP)]₂ to generate Ru^(OEP)Cl₂ (C. Sishta, M.Sc.Thesis, University of British Columbia, 1986) show that solvent plays a major role in directing this oxidation reaction. A reaction stoichiometry of 4:1 between HCI and [Ru(OEP)]₂ in C₆D₆ or C₇D₈ showed that HCI itself was the oxidant and not trace Cl₂ in HCI, as thought previously. A range of HX acids having pK[subscript]a, values in the range 38 to less than -10 (HX = H₂, MeOH, H₂0, H₂S, CH₃COOH, C₆H₅COOH, HF, CF₃COOH, HN0₃, HBF₄, HCI. HBr, and HSbF₆) were tested for reactivity with [Ru(OEP)]₂in C₆D₆; the data showed that a strong acid (pK[subscript]a < ca. 0) was necessary to initiate reactivity. The complex Ru[superscript]Ⅳ(OEP)(SbF₆)₂ was generated in situ by reacting HSbF₆ with [Ru(OEP)]₂. In CH₂C1₂, a 1:1 stoichiometric reaction between HCI and [Ru(OEP)]₂ was observed, instantly fanning a mixture of products, tentatively formulated as Rura(OEP)H and [Ru[superscript]Ⅲ(OEP)]₂CHCl₂ based on spectroscopic data. The species proved impossible to separate. These same products were formed slowly by the reaction of [Ru(OEP)]₂ with CH₂C1₂ in the absence of HCI, and kinetic studies suggest that a direct reaction of [Ru(OEP)]₂ with CH₂C1₂ is likely, rather than reaction of [Ru(OEP)]₂ with impurities in CH₂C1₂. The product mixture generated Ru(OEP)Cl₂ upon further reaction with HCI, both in the absence and in the presence of air. The complex Ru[superscript]Ⅳ(OEP)(BF₄)₂ was generated in situ by an analogous reaction of aqueous HBF₄ with the product mixture. The required hydrogen-containing co-product from the reaction of HX (X = Br, CI) with [Ru(OEP)|₂ in C₇D₈ or CH₂C1₂ was not detected, but was shown not to be H₂. Oxidation of Ru(porp)(CH₃CN)₂ and Ru(OEP)py₂ (py = pyridine; porp = OEP, TMP (the dianion of tetramesitylporphyrin)) by gaseous HX (X = Br, CI) in the absence of air yielded Ru[superscript]Ⅳ(porp)X₂ complexes. The new compound Ru(TMP)Br₂ was synthesized by this method using the bis(acetonitrile) precursor, and was characterized by spectroscopy; the chloride analogue Ru(TMP)Cl₂ was generated in situ. The magnetic properties (susceptibility and moment) of Ru(OEP)Br₂ from 6 to 300 K are unlike those reported for ruthenium(IV) non-porphyrin complexes, and reveal a significant contribution from temperature-independent paramagnetism. The reaction of Ru(OEP)X₂ (X = Br, CI) with NH₃ gave the complexes Ru[superscript]Ⅲ(OEP)X(NH₃), which upon acidification under an inert atmosphere yielded the Rum(OEP)X compounds. These Ru111 complexes were characterized by spectroscopic techniques, and the solution chemistry of the five-coordinate species Ru(OEP)X was developed: the Ru[superscript]Ⅲ(OEP)X(CH₃CN) species were also characterized. Solvation of the five-coordinate species Ru(OEP)X (X = Br, CI) was observed in coordinating solvents to form the six-coordinate species Ru(OEP)X(solvent) (solvent = py, CH₃CN and MeOH). Estimates of the equilibrium constants for the association of these ligands to Ru(OEP)X were obtained from UV/visible titration experiments in CH₂C1₂. Similarly, the equilibrium constant for the association of Br to Ru(OEP)Br to generate in situ (n-Bu)₄N⁺[Ru[superscript]Ⅲ(OEP)Br⁺₂]", was measured. Disappointingly, the complexes Ru(OEP)X were shown not to catalyze the oxidation of organic substrates such as cyclohexene. Electrochemical and spectroelectrochemical studies of the complexes Ru(OEP)X₂ and Ru(OEP)X (X = Br, CI) showed that the Ru[superscript]Ⅳ/Ru[superscript]Ⅲ couple occurred at 480-460 mV and 950-870 mV vs. NHE, respectively, and that the probable reductant for the reaction of Ru(OEP)X₂ with NH₃ was NH₃ itself. A facile reduction of Ru(OEP)(SbF₆)₂ gave the complex Ru[superscript]Ⅲ(OEP)SbF₆, by a probable homolysis of the Ru-F bond. The outer-sphere oxidation of Ru(OEP)py₂ by air in the presence of HX acids gave the isolated or in situ characterized complexes [Ruin(OEP)py₂]+ X" (X = CI, Br, F, BF₄). Similar oxidation of Ru(OEP)(CH₃CN)₂ formed [Ru(OEP)(CH₃CN)₂]+ Br-. Electrochenucal studies showed that 0₂ in acidic media was capable of oxidizing the Ru(OEP)(solvent)₂ complexes (solvent = py, CH₃CN) to the Ru[superscript]Ⅲ complexes, presumably generating H0₂ .

Abstract (sommario):

This thesis describes two projects involving the organometallic chemistry of iron and ruthenium complexes with DMPE ligands [DMPE = 1,2-bis(dimethylphosphino)ethane]. The first study involves an investigation into the kinetics and mechanisms of OH bond activation reactions of [Fe(DMPE)2]. The second project involves an investigation into the synthesis of RuH2(DMPE)2, the formation and properties of trans-[RuH(n2-H2)(DMPE)2]*, and the reactions of RuH2(DMPE)2 with alkyl and aryl thiols. In Part I of this work, the kinetics of the cis/trans isomerization of FeH(C6H5)(DMPE)2 and FeD(C6D5)(DMPE)2 were measured by 31P NMR spectroscopy in pentane and THF. The isomerization reactions follow first-order reversible kinetics. FeH(C6H5)(DMPE)2 and FeD(C6D5)(DMPE)2 also undergo exchange with added arenes in a concerted fashion at the iron centre. The rate of exchange is comparable to the rate of isomerization. From the equilibrium constant for the exchange reaction, it was found that FeH(C6H5)(DMPE)2 is thermodynamically more stable than FeD(C6D5)(DMPE)2 by approximately 3 kJ mol'1 in pentane. FeH(C6H5)(DMPE)2 and FeD(C6D5)(DMPE)2 react with diethyl disulfide to give Fe(SEt)2(DMPE)2. The reaction proceeds via loss of benzene or benzene-d6 followed by addition of [Fe(DMPE)2] to the 8-8 bond of EtSSEt. By following the kinetics of the reactions of EtSSEt with FeH(C6H5)(DMPE)2 and FeD(C6D5)(DMPE)2 in THF separately, the rates of reductive elimination of benzene OH and GD bonds at 283 K were found to be 3.9 x 10‘ s-1 and 6.5 x 104 s-1 respectively. The inverse deuterium isotope effect (k”/kD = 0.6) can be rationalized by the presence of a n-benzene intermediate in the elimination reaction. In solution, the phenyl ring in cis'FeH(C6H5)(DMPE)2 assumes a fixed orientation and is constantly flipping at 240 K. During this work, it was discovered that [Fe(DMPE)2] is capable of catalyzing the hydrogenation of alkenes to alkanes under photochemical conditions. The hydrogenation reaction competes with a significantly slower dehydrogenation reaction. A quantitative analysis of the efficiency of [Fe(DMPE)2] as a hydrogenation catalyst was carried out. The hydrogenation of cyclopentene is faster than that of tenninal alkenes. A reaction cycle is proposed for the hydrogenation-dehydrogenation reactions mediated by Fe(DMPE)2 complexes. Treatment of an irradiated sample of FeH(cyclopenteny1)(DMPE)2 with dibromomethane afforded FeBr2(DMPE)2 and trans-[Fe(cyclopentenyl)Br(DMPE)2]Br.2H20 whose crystal structures are presented. In Part II, a synthesis of Rqu(DMPE)2 from trans-RuC12(DMPE)2 by reduction with sodium/Z-propanol is presented. Protonation of RuH2(DMPE)2 with weak organic acids such as methanol, ethanol and thiols affords the molecular hydrogen complex trans-[RuH(T]2-H2)(DMPE)2]+ which has a nZ-bound H2 ligand and a 6-bound hydride ligand. T1 measurements and 1JHD coupling in nZ-HD ligand confirm the 'non-classical' structure. Between 220 and 300 K, the molecular hydmgen complex continuously undergoes intermolecular exchange with the protonating solvent and all the rutheniumbound hydrides undergo intramolecular exchange. In methanol, a previously unreported five-coordinate ruthenium(II) complex, trans-[RuH(DMPE)2]+, exists in equilibn'um with the molecular hydrogen complex. Reactions of the ruthenium dihydride with alkyl- and arylthiols afford trans-monothiolate hydrides. Aromatic thiols react more rapidly than alkanethiols. The reaction is believed to proceed via protonation of the dihydride (by the acidic thiol group) to give the molecular hydrogen complex, followed by substitution of the 'r12-H2 ligand with the conjugate base of the thiol. The dithiolate complex trans-[Ru(SPh)2(DMPE)2] has been isolated and its X-ray crystal structure is presented. In dithiols, dithiaruthenocycles are not formed, which is in contrast with the formation of the iron analogues. Although protonation of RuH2(DMPE)2 with alcohols is facile, substitution of trans-[RuH(T]2-H2)(DMPE)2]* by alkoxide ions does not take place in the presence of thiolate ions.

Abstract (sommario):

The oxidation of three alkyl thioethers, phenol and 2-propanol by trans-dioxo ruthenium porphyrin species, and the synthesis, characterization and reactivity of several new ruthenium porphyrin complexes are described in this thesis. The trans-dioxo species Ru(Porp)(O)₂ [Porp= the dianions of 5,10,15,20-tetramesitylporphyrin (TMP) and 5,10,15,20-(2,6-dichlorophenyl)porphyrin (OCP)] selectively oxidize diethyl-, di-n-butyl- and decylmethyl- sulfides to the corresponding sulfoxides at room temperature. The reaction is first order in [Ru] and in [thioether]. The second order rate constants for the first O-atom transfer from the Ru(TMP) system are: 7.54xl0⁻³, 1.23xl0⁻² and 1.14x10-¹ M⁻¹ s⁻¹ respectively for the three thioethers at 20.0 °C. The activation parameters for the O-atom transfer process are also determined: for Et₂S, ∆H‡= 58.3 kJ mol⁻¹ and ∆S‡= -86 J K⁻¹ mol⁻¹; for nBu₂S, AH‡= 47.4 kJ mol⁻¹and ∆S‡= -120 J K⁻¹ mol⁻¹; for DecMeS, ∆H‡= 56.5 kJ mo⁻¹ and ∆S‡= -70 J K⁻¹ mol⁻¹. A second order rate constant of 7.23xl0⁻²M⁻¹s⁻¹ is measured at 20.0 °C for the oxidation of Et₂S by Ru(OCP)(O)₂. The intermediates Ru(TMP)(OSEt₂)₂, Ru(TMP)(OSEt₂)(OSEt₂) and the final product Ru(TMP)(0SEt₂)₂,where O and S refer to O- and S- bonded sulfoxide, are observed by ¹H nmr, and the last mentioned is isolated and characterized. A mechanism is proposed, based on electrophilic attack of the O=Ru=O moiety on :SR₂ to form bis-O-bonded species which subsequently isomerizes to bis-S-bonded species via mixed species. The Ru(TMP)(O)₂/Et₂S/O₂ system at room temperature is catalytic in complex, but produces only about 5 turnovers due to poisoning of the catalyst by the reaction product. The same system at >65 °C gives higher turnovers, but now porphyrin ligand degradation is observed, perhaps via oxidation by the O=Ru=O moiety. The Ru(OCP)(0)₂/Et₂S/O₂ system at 100 °C catalytically oxidizes Et₂S to Et₂SO and Et₂SO₂ (in ~ 4:1 ratio) and the porphyrin ligand does not undergo oxidative destruction. The Ru(TMP)(O)₂ species reacts with phenol via an observed intermediate Ru(TMP)(p-O(H)C₆H₄OH)₂ to form Ru(IV)(TMP)(OC₆H₄OH)₂, a paramagnetic (S=l) complex which is isolated and characterized. The oxidation reaction is first order in both [Ru] and [phenol] with a second order rate constant 6.90x10⁻² M⁻¹ s⁻¹at 20.0 °C. A mechanism based on electrophilic attack by the O=Ru=O moiety on the aryl ring followed by proton migration is proposed. This mechanism also explains the formation of some free para-benzoquinone and 1 equivalent of water per Ru. No ortho-benzoquinone is formed in the reaction. Preliminary ⁻H nmr studies reveal that 2-propanol is oxidized to acetone by Ru(TMP)(O)₂. A paramagnetic species (S= 1) was isolated as the only porphyrin product but not characterized. A range of novel ruthenium porphyrin complexes is also prepared. The reaction of acetylene with the four-coordinate Ru(TMP) species forms [Ru(TMP)]₂(u-C₂H₂), the first reported organometallic ruthenium porphyrin dimer. The complexes, Ru(TMP)(PhCCPh) and Ru(TMP)(PhCCH), the first π-bonded alkyne species in ruthenium porphyrin chemistry, are characterized in solution. The π-bonded alkene complexes Ru(TMP)(CH₂CH₂) OPrOH).(iPrOH) and Ru(TMP)(CH₂CH₂) are isolated and characterized, while the Ru(TMP)(cyclohexene) complex is characterized in situ. The Ru(TMP)(OSEt₂)₂ complex is isolated also by the reaction of Ru(TMP)(CH₃CN)₂with Et₂SO. The Ru(TMP)(L)₂ complexes, L= OSMe₂, OSnPr₂ and OSnBu₂ are also prepared via the above method and characterized. Some new Ru(OCP) complexes, (the monocarbonyl, the bis-acetonitrile and the dioxo- species) are also isolated and characterized.

Abstract (sommario):

This thesis reflects two main aims. Firstly, the synthesis and characterisation of a number of potential anion receptors was undertaken and their anion binding properties were assessed. In so doing, a second aim was fulfilled, namely a comparison of the various methods of detecting the bound anion, and quantifying the binding strength. Four techniques appear in this thesis; ¹H nuclear magnetic resonance, UV-visible spectroscopy, electrochemistry and luminescent emission. Quantitative titrations were performed and, where possible, stability constants estimated. Chapter One provides an introduction to some of the themes of molecular recognition and provides a brief overview of the literature associated with anion recognition. A Prologue describes the design of the receptors studied; they all incorporate a metal centre and appended amide groups which provide sources of hydrogen bonding. The molecules are mostly cationic and a combination of positive charge and hydrogen bonding constitutes the binding interaction. Chapter Two is concerned with receptors based on cobalticinium, [Cp₂Co]⁺ . A number of receptors are presented and are found to bind anions with stability constants typically in the range of 500-1000 dm³mol^-1 . Receptors involving more than one cobalticinium centre are found to bind much more strongly and, furthermore, variations in functional groups appended close to the proposed coordination site impart selectivity; dihydrogen phosphate is bound more strongly than chloride. It is also found that different techniques give different stability constants and comment is made on this phenomenon. Chapter Three examines the role of positive charge in anion binding and describes the synthesis and coordination properties of several neutral receptors. These molecules retain hydrogen bonding sites, and it is found that this is sufficient to bind anions, but the strength of the interaction is greatly reduced. Chapter Four introduces another system, based on RuL(bpy)₂²⁺ , where L is a 4,4'-amide disubstituted bpy. The strength of binding is an order of magnitude greater than the cobalticinium systems as detected by several methods including emission studies, which are very sensitive. Comparison with a neutral, rhenium-based receptor is made. A dihydrogen phosphate-selective luminescent sensor is also presented. The Epilogue identifies areas for future research. Specialised introductions and summaries are found at the beginning and end of each chapter.

Abstract (sommario):

Olefin metathesis is a valuable synthetic tool, widely used in several fields of science. Due to the importance of this transformation several contributions have been made in this field in order to understand mechanistic aspects, reactivity and applicability of this process. In this topic, ruthenium indenylidene complexes have shown great activity and stability in metathesis, making them very valuable pre-catalysts. However, several aspects of these pre-catalysts have not been evaluated yet. For example, even though reports of active second generation ruthenium indenylidene complexes bearing bulky N-heterocyclic carbenes are present in the literature, no studies have been done to understand how steric hindrance affects the process. For these reasons, [RuCl₂(IPr*)(PPh₃)(3-phenylindenylidene)] (IPr*-PPh₃) and [RuCl₂(IPr*)(Py)(3-phenylindenylidene)] (IPr*-Py), bearing the very bulky ligand, IPr* have been synthesised and compared with [RuCl₂(IPr)(PPh₃)(3-phenylindenylidene)] (IPr-PPh₃) and the new [RuCl₂(IPr)(Py)(3-phenylindenylidene)] (IPr-Py). Another important aspect, presented in this thesis, is the investigation of the stability of indenylidene pre-catalysts in alcohol solvents. Surprisingly, several different decomposition processes occur depending on the starting complex and the alcohol used. Mechanistic investigation into this decomposition, allowed us to develop a better understanding of this process, and to predict the decomposition product based on the environment. In particular, this study revealed that [RuCl(η⁵-3-phenylindenyl)(PPh₃)₂] (Eta-5) is accessed from [RuCl₂(3-phenylindenylidene)(PPh₃)₂] (M₁₀) via a novel indenylidene to η⁵-indenyl rearrangement. This formal decomposition product has been found to be active in at least 20 different catalytic transformations, rendering it a versatile catalytic tool.

Abstract (sommario):

Includes bibliographical references.
3 v. :
Details research carried out into the nonlinear optical properties of metal alkynyls, chiefly organoruthenium complexes, showing that these complexes can be designed to have very large NLO coefficients. Also demonstrates the utility of spectroscopic, electrochemical and copmutational aids as predictive tools for NLO materials. Also examines cluster synthesis, reactivity and physical properties using ruthenium clusters and hard-donor ligands, affording a series of cluster complrxes that provide structural models for industrially-important hydrotreating intermediates.
