Chemistry of higher order, mixed organocuprates. reactions of α,β-unsaturated ketones.

Bruce H. Lipshutz; Robert S. Wilhelm; Joseph A. Kozlowski

Abstract Organocuprates of general formula R 2 Cu(CN)Li 2 react rapidly with α,β-unsaturated ketones at low temperatures and in high yields to deliver ligands in a conjugate manner. These reagents apparently do not require the use of additives for stabilizing or solubilizing purposes.
