Abstract
Low temperature 1H NMR analysis of a reaction mixture containing a vin ylic zirconocene, MeLi, Me(3)ZnLi, 20 mol % Me(2)Cu(CN)Li-2 and an eno ne, reagents which together lead to the Michael delivery of a vinyl li gand, reveals the presence of a zinc enolate, the species likely to be responsible for the subsequent alkylation or aldol reaction as the fi nal step in 3-component couplings.
