摘要：

Methods for the highly stereoselective and regiodivergent hydrosilylation of 1,3-disubstituted allenes have been developed. The synthesis of Eallylsilanes is accomplished with palladium NHC catalysts, and trisubstituted Zalkenylsilanes are accessed with nickel NHC catalysts. Unsymmetrically substituted allenes are well tolerated with nickel catalysis and afford Zalkenylsilanes. Evidence for a plausible mechanism was obtained through an isotopic double-labeling crossover study.
