Abstract–The reaction of bis-(2-pyridylmethyl) cyanocuprate (3) with a variety of α, β- unsaturated carbonyl compounds is reported. It has been found that while the reaction with enone goes through a 1, 2-addition path, the outcome of the reaction with α, β-unsaturated esters depends on the structure of the electrophile, giving the conjugate addition product with γ-hetero-substituted α, β-unsaturated esters. On the other hand, the reaction of 3 with ...
