Reactivity of a coordinatively unsaturated Cp*Ru(κ2-P,O) complex

Abstract

Whereas a new coordinatively unsaturated Cp*Ru(κ²-P,O) complex (1a) forms adducts with two-electron donors (including σ-H₂ and µ-N₂ ligands), double Si–H bond activation is observed upon treatment with Ph₂SiH₂ or PhSiH₃, leading to the clean formation of products corresponding to the net insertion of a Ph₂Si: or Ph(H)Si: fragment into the Ru–O bond of 1a.
