Synthesis and Structure of a Hydrido(hydrosilylene)ruthenium Complex and Its Reactions with Nitriles

摘要

Transition-metal-silylene complexes have attracted much attention during the last two decades,as they are considered key intermediates in various transformation reactions of organosilicon compounds.Numerous silylene complexes have been prepared and their reactivities investigated,but clear-cut reactions of silylene complexes with substrates have been limited,because two bulky groups on the silylene ligand,which have been necessary to stabilize the silylene complexes,only allowed access of very small substrate molecules to the reactive silylene silicon site.Recently,Tilley et al.
