The oxidation of the Pt(IV) tetramethyl complex [Ar{single bond}N{double bond, long}CH{single bond}CH{double bond, long}N{single bond}Ar]PtMe4 (Ar = 2,6-Me2C6H3) has been investigated in acetonitrile and dichloromethane. Cyclic voltammetry demonstrates that the irreversible oxidation of [Ar{single bond}N{double bond, long}CH{single bond}CH{double bond, long}N{single bond}Ar]PtMe4 occurs at a slightly less positive oxidation potential than the irreversible oxidation of the analogous Pt(II) species [Ar{single bond}N{double bond, long}CH{single bond}CH{double bond, long}N{single bond}Ar]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 Pt{single bond}C bond in [ArN {double bond, long} CH {single bond} CH {double bond, long} NAr] PtMe4{radical dot} + is involved in the oxidatively induced reactions.
