摘要

Silicon-hydrogen bonds are shown to add to a nickel carbon double bond to yield nickel alpha-silylalkyl hydrido complexes. Kinetic and isotope labeling studies suggest that a concerted 4-centred addition across the NiQC bond is operative rather than a mechanism involving Si-H oxidative addition. This constitutes an example of Si-H bond activation via ligand cooperativity.
