Transition Metal Silyl Complexes. 60. † ,1 Enhanced Reactivity of a Platinum Dimethyl Complex toward Trimethoxysilane Due to a P,N-Chelating Co Ligand

[(κ2-P,N)-Me2NCH2CH2PPh2]PtMe2 reacts with trimethoxysilane to yield the methyl trimethoxysilyl complex [(κ2-P,N)-Me2NCH2CH2PPh2]Pt[Si(OMe)3]Me, the bis(trimethoxysilyl) complex [(κ2-P,N)-Me2NCH2CH2PPh2]Pt[Si(OMe)3]2, methyltrimethoxysilane, tetramethoxysilane, and small amounts of pentamethoxydisiloxane and hexamethoxydisiloxane. The formation of these compounds can be explained by Si−H oxidative addition/reductive elimination as well as Si−O activation and scrambling reactions of the silicon substituents.
