way: Regio‐ and enantioselective allylic substitution with a silicon nucleophile generated by copper(I)‐catalyzed SiB bond activation provides direct access to α‐chiral allylicsilanes from linear acceptors. The enantioconvergent catalysis employing McQuade's six‐membered N‐heterocyclic‐carbene–copper(I) catalyst is applicable to aryl‐ and alkyl‐substituted allylic phosphates (see scheme).
