Abstract
[(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 amou nts of pentamethoxydisiloxane and hexamethoxydisiloxane. The formation of t hese compounds can be explained by Si-H oxidative addition/reductive elimin ation, as well as Si-O activation and scrambling reactions of the silicon s ubstituents.
