Transition Metal Silyl Complexes. 60.,1 Enhanced Reactivity of a Platinum Dimethyl Complex toward Trimethoxysilane Due to a P,N-Chelating Co Ligand
摘要:
[(kappa(2)-P,N)-Me2NCH2CH2PPh2]PtMe2 reacts with trimethoxysilane to yield the methyl trimethoxysilyl complex [(kappa(2)-P,N)-Me2NCH2CH2PPh2]Pt[Si(OMe)(3)]Me, the bis(trimethoxysilyl) complex [(kappa(2)-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.
