Carboalumination/transmetalation/conjugate addition: a new catalytic copper(I)-induced process for the 1,4-delivery of vinylic groups to enones
摘要:
Exposure of vinylalanes, derived from carbometalations of 1-alkynes, to catalytic amounts of CuCN.2LiCl in the presence of an alpha,beta-unsaturated carbonyl group affords products of vinylic ligand transfer in a 1,4-manner.
