The Pt(IV) complex (tBuMe2nacnac)PtMe3 (1, tBuMe2nacnac = [((4-tBu-2,6-Me2C6H2)NC(CH3))2CH]) reacts with molecular oxygen to form a peroxo complex, 2, in which one oxygen atom is bound to the platinum center and the other to the central carbon of the nacnac ligand backbone. Over time, 2 converts to a new Pt(IV) species (3) wherein the oxygen−oxygen bond has been cleaved.
