Ruthenium(IV) silyl hydride complexes via reaction of silanes with 16-electron [Ru(η5-C5Me5)(PPri3)X](X = Cl, CH2SiHPh2, SiMePh2) complexes. Hydride migrations to an η2-silene ligand

Abstract

Reactions of [Ru(η⁵-C₅Me₅)(PPrⁱ₃)(H)(η²-CH₂SiPh₂)] with hydrosilanes occur via initial migration of hydride to the silene ligand, and eventually give disilyl hydride or silyl dihydride ruthenium(IV) complexes; the 16-electron chloride[Ru(η⁵-C₅Me₅)(PPrⁱ₃)Cl] adds mesityl (Mes) silane to give [Ru(η⁵-C₅Me₅)(PPrⁱ₃)(H)₂(SiHcMes)] which was crystallographically characterized.
