Dirhodium(II) tetrakis(perfluorobutyrate)-catalyzed 1,4-hydrosilylation of α,β-unsaturated carbonyl compounds

The use of dirhodium(II) catalysts in the 1,4-hydrosilylation of alpha,beta-unsaturated ketones and aldehydes was explored. Dirhodium(II) tetrakis(perfluorobutyrate), Rh-2(Pfb)(4), proved to be the catalyst of choice for this process, providing the corresponding silyl cool ethers in high yields.
