Reactions of coordinated organosilanes: cobalt carbonyl complexes of ethynylhydrogenosilanes

Article abstract of DOI:10.1016/0022-328X(89)85155-1

Cobalt carbonyl complexes of mono-, di- and tri-ethynylsilanes containing silicon-hydrogen bonds are obtained by selective-coordination of the triple bond in ethynylhydrogenosilanes.The silicon-hydrogen bond of the coordinated ethynylsilanes reacts spontaneously with methanol, water, benzaldehyde and phenylacetylene.The silicon-hydrogen bonds in the ethynylsilane-cobalt carbonyl complexes show enhanced reactivity in hydrosilylation.
