Reaction of molecular oxygen with the methylplatinum(II) complex K[(魏²-NNO)Pt^II(CH₃)(OH)] (3; NNO = bis(3,5-dimethylpyrazol-1-yl)acetate) in D₂O results in oxidation to (魏³-NNO)Pt^IV(CH₃)(OD)₂ along with competitive methyl transfer to produce (魏³-NNO)Pt^IV(CH₃)₂(OD). Methyl transfer is favored under more alkaline conditions and at higher temperatures. Mechanistic studies are consistent with the direct reaction of 3 with molecular oxygen as a common first reaction step on the path to both products.
