In the presence of chiral thiourethane ligands [Cu(MeCN)4]BF4 forms active catalysts for the conjugate addition of MeMgBr, ZnEt2 and AIR3 (R = Me, Et) to non-3-en-2-one, hept-3-en-2-one, and 5-methylhex-3-en-2-one. Enantioselectivities of up to 51% are realised for these difficult substrates; for cy
