C−H activation is observed in reactions of [(diimine)Pt(μ2-OH)]22+ dimers with allylic and benzylic C−H groups. The reactions proceed in good yields under mild conditions. Mechanistic studies indicate that the active species is the monomeric [(diimine)Pt(OH2)]2+ dication. The related palladium species, [(diimine)Pd(μ2-OH)]22+, exhibit similar stoichiometric activations and also effect catalytic oxidation
