Abstract:
Oxidation reactions of both inorganic and organic substrates are among the most important chemical transformations, with application in sustainable chemistry and chemical synthesis. A library of half sandwich IrIII oxidation complexes with varying ligands were synthesised (54-78% yield) and fully characterised (NMR, UV-vis, crystal data), in order to investigate the effect on catalyst activity for water and C-H oxidation reactions. The electrochemical transition of IrIII to IrIV was investigated (cyclic voltammetry (CV)) and found to vary between ligand sets, such that alkyl substituted compou

Abstract:
Cisplatin has been used to treat various types of cancers for over 30 years, however, a number of serious side-effects of cisplatin have stimulated the quest for other metal-based anticancer agents. Iridium complexes are generally thought to be too inert to possess high reactivity, and therefore, there are only a few previous reports of the antitumour activity of iridium complexes. In this thesis a wide range of organometallic IrIII cyclopentadienyl complexes of the type [(η5-Cpx)Ir(XY)Cl]0/+ (where Cpx = pentamethylcyclopentadienyl (Cp*), tetramethyl(phenyl)cyclopentadienyl (Cpxph) or tetrame

This thesis presents ultrafast photophysical measurements on a number of phosphorescent iridium complexes and establishes relationships between the relaxation rates and the vibrational properties of the material. When ultrafast luminescence is measured on the peak of the phosphorescence spectrum and on its red-side, 230 fs and 3 ps decay time constants were observed in all materials studied, and this was attributed to population redistribution amongst the three electronic substates of the lowest triplet metal-ligand charge transfer (MLCT) state.

Abstract:
This thesis investigates the use of aluminium trichloride and acetyl chloride to functionalise saturated hydrocarbons and probe the mechanism by which this functionalisation occurs. It also looks at the use of iridium catalysis to form carbon-boron bonds from carbon-hydrogen bonds in naphthalenediimides or NDIs. Chapter one reviews work published in the field of carbon-hydrogen bond functionalisation; from the traditional reactions of hydrocarbons as simple as combustion to cutting-edge selective C-H activation in natural product synthesis. Chapter two investigates experimentally the mechanism

Abstract:
This thesis describes the formation of iridium fluoroacyl compounds by reaction of XeF<SUB>2</SUB> with Ir(I) compounds, and the reactivity of some of these fluoroacyl species. Reactions of [Ir(CO)<SUB>3</SUB>L<SUB>2</SUB>][AsF<SUB>6</SUB>] with XeF<SUB>2</SUB> led to the fluoroacyl compounds [Ir(CO)<SUB>2</SUB>(COF)FL<SUB>2</SUB>][AsF<SUB>6</SUB>] for L = PEt<SUB>3</SUB>, PMe<SUB>3</SUB>, PMe<SUB>2</SUB>Ph, PEt<SUB>2</SUB>Ph and PEtPh<SUB>2</SUB> but not for L = PMePh<SUB>2</SUB>, PPh<SUB>3</SUB> and PCy<SUB>3</SUB>.
