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

  摘要：

  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 alpha,beta-unsaturated ketones regio- and stereoselectively.

  The formal hydroacylation reaction of allenes has been developed employing carboxylic anhydrides as acyl sources and hydrosilanes as reducing reagents in the presence of a commercially available palladium complex as a catalyst. The reaction affords α,β-unsaturated ketones regio- and stereoselectively. The similar catalyst system is also effective for the reduction of carboxylic anhydrides to the corresponding

  在市售的钯配合物作为催化剂的存在下，已经开发了使用羧酸酐作为酰基源和氢化硅烷作为还原剂的丙二烯的正式加氢酰化反应。该反应区域和立体选择性地提供α，β-不饱和酮。相似的催化剂体系对于使用氢化硅烷将羧酸酐还原为相应的醛也是有效的。
