The near-quantitative transformation of a racemic cyclic allylic phosphate to a highly enantiomerically enriched allylic silane by allylic substitution with a silicon nucleophile is reported. The reaction is catalyzed by a chiral NHC–copper(I) comp

A full account of our work on enantioselective silylation of typical prochiral acceptors employing chiral six-membered NHC–copper(I) complexes introduced by McQuade and co-workers is presented. With these precatalysts, asymmetric branched-selective
