CuX3Li2-catalysed conjugate addition of dialkylmagnesium reagents to α,β-unsaturated carbonyl compounds
Abstract
Copper salts of the type CuX3Li2(X = halogen) catalyse the conjugate addition of dialkylmagnesium compounds to α,β-unsaturated carbonyl compounds in the presence or absence of Me3SiCl as an additive, the organomagnesium compounds being prepared from α-olefins, hydrogen and magnesium according to the procedure of Bogdanović.
