Palladium-Catalyzed Formal Hydroacylation of Allenes Employing Acid Chlorides and Hydrosilanes

Abstract

The palladium-catalyzed formal hydroacylation of allenes employing acid chlorides and hydrosilanes has been achieved. The reactions proceed with commercially available Pd(OAc)2 as a catalyst and HSi(iPr)3 as a reducing reagent, giving the corresponding α,β-unsaturated ketones regio- and stereoselectively.
