The complex [PtMe2({kappa(2)-N,N-RNQCH-2-C5H4N})] reacts with oxygen in acetone solution to give the platinum(IV) complex [Pt(OH)Me-2-{kappa(3)-N, N, O-RNH-CH(2-C5H4N)(CHQCMeO)}], when R = 2-C6H4OH, but not when R = Ph. It has been suggested that the phenol substituent plays two key biomimetic roles; firstly, in proton coupled electron transfer reactions in the activation of oxygen and hydroperoxide groups and, secondly, in proton relay from a methyl group of the coordinated acetone.
