[Rh(OH)(cod)]2 (cod: 1,5-cyclooctadiene) is found to be a highly efficient catalyst for 1,4-hydrosilylation of α,β-unsaturated carbonyl compounds leading to enolsilanes. The reaction of 2-cyclohexen-1-one with HSiMe(OEt)2 in the presence of 0.005 mol% of the catalyst without solvent furnishes the corresponding enolsilane in 97% yield at room temperature within 10 min.
