Book excerpt: This thesis describes the synthesis and reactivity of platinum(II) and platinum(IV) complexes with mixed donor ligands containing [P, N, C] and [P, N, O] donor sets derived from iminophosphines and phosphinoamides. Chapter 1 introduces the concepts and principles, like hemilability, that influence the formation of stable complexes and how this stabilisation can influence the reactivity of the complex. This is highlighted using aminophosphines and iminophosphines as examples. In order to present the application of these mixed-donor complexes, a comprehensive overview of platinum complex chemistry, including Pt(IV) complexes, trans complexes and cyclometallates, in medicine is given. Chapter 2 reports the coordination chemistry of two types of [P, N, C] donor ligands; iminophosphines HL1-4 and phosphinoamides HL5-7 to generate a novel library of monodentate, bidentate and tridentate cyclometallated Pt(II) species by a variety of methods. Chapter 3 describes the synthesis of novel ionic, monophosphine substituted Pt(II) complexes of [P, N, C] and [P, N, O] ligands. The iminophosphine ([P, N, C] and [P, N, O]) complexes underwent substitution with all three of the phosphines introduced. However, the success of the reaction of the iminolphosphine [P, N, C] complexes depended on the nature of the phosphine used. This leads to the conclusion that substitution reactions of iminolphosphine complexes are influenced by a combination of basicity and steric bulk of the incoming ligand. Chapter 4 reports the oxidation of bidentate and cyclometallated Pt(II) complexes to generate a novel series of Pt(IV) species. Additionally it reports 1H and 31P{1H} NMR investigations into the reduction of Pt(IV) by low molecular weight thiols and finally describes the reaction of the Pt(II) cyclometallates with the same low molecular weight thiols. All compounds synthesised in chapters 2-4 were characterised by elemental analysis, IR, 1H and 31P{1H} NMR spectoscopies. Selected complexes were also analysed using single X-ray crystal analyses and mass spectrometry.
