The oxidation of the Pt(IV) tetramethyl complex [ArNCHCHNAr]PtMe4 (Ar = 2,6-Me2C6H3) has been investigated in acetonitrile and dichloromethane. Cyclic voltammetry demonstrates that the irreversible oxidation of [ArNCHCHNAr]PtMe4 occurs at a slightly less positive oxidation potential than the irreversible oxidation of the analogous Pt(II) species [ArNCHCHNAr]PtMe2. The product distribution arising from the oxidation depends strongly on the reaction conditions and includes cationic Pt(IV) species (acetonitrile, dichloromethane solvents) and Pt(II) species (dichloromethane only). Evidence is presented that suggests that homolytic cleavage of a weakened PtC bond in [ArNCHCHNAr]PtMe4+ is involved in the oxidatively induced reactions.
