Platinum-carbon bond formation by cyclometallation and oxidative addition reactivity of organoplatinum compounds

The work described in this thesis stems from the observation that a pyrazolyl group in Me2Pt(HCpz3) umdergoes a Cyclometallation reaction when heated in neat pyridine, giving rise to a NC- coordination mode, which is uncommon for flexible carbon bridged maltidentate ligands.... The chemistry of this novel cyclometallation system has been explored, together with related polydentate ligand systems and the oxidative addition reactivity of platinum(II) complexes, in order to extend our knowledge of reactivity of platinum(II) toward formation of organoplatinum(II) and platinum(IV) complexes with new structural features. A range of polydentate pyrazolyl ligands were chosen, or designed and synthesized, according to their ability to possibly undergo cyclometallation reactions.
