M. Vanklaveren et al., ARENETHIOLATOCOPPER(I) COMPLEXES AS HOMOGENEOUS CATALYSTS FOR MICHAELADDITION-REACTIONS, Tetrahedron letters, 35(33), 1994, pp. 6135-6138
Arenethiolatocopper(I) complexes are shown to be efficient homogeneous
catalysts in Michael addition reactions of several Grignard reagents
to acyclic enones; the addition products are formed with excellent che
moselectivity (>99%) and good enantioselectivity (76% e.e.).
