A dehydrogenative coupling between enolizable carbonyl compounds and equimolar amounts of triorganosilanes catalyzed by a tethered ruthenium complex with a Ru-S bond is reported. The complex is assumed to fulfill a dual role by activating the Si-H bond to release a silicon electrophile and by abstracting an α-proton from the intermediate silylcarboxonium ion, only liberating dihydrogen as the sole byproduct. Reaction rates are exceedingly high at room temperature with very low loadings of the ruthenium catalyst.

Methylplatinum triflate coordinated with 1,2-diphenyl-3,4-bis[(2,4,6-tri-t-butylphenyl)phosphinidene]cyclobutene serves as a highly selective catalyst for dehydrogenative silylation of ketones with HSiMe2Ph in the presence of pyridine as a co-c

A highly convenient two-step sequence for the regiospecific synthesis of cyclic silyl enol ethers has been developed involving the 1,2-addition of dimethyl(phenyl)silyllithium to cyclic α,β-unsaturated ketones followed by the treatment of the resulting silyl carbinols with a catalytic amount of NaH in THF at 25°C.
