A new convenient route to the bis[(trimethylstannyl)vinyl] cuprate reagent 9 is described. Its addition to alpha,beta-unsaturated ketones has been studied, Bis(trimethylsilyl)acetamide (BSA) was found to activate 1,4-conjugate addition of 9 to alpha,beta-unsaturated ketone esters without concomitant reduction of the double bond.
