The reaction of tributyltin enolates, prepared from tributyltin methoxide and enol acetates <I>in situ</I>, with aryl and 1-alkenyl bromides in the presence of dichlorobis(tri-<I>o</I>-tolylphosphine)palladium was found to give α-aryl and α-(1-alkenyl) ketones, respectively, in good yields with essentially complete retention of the enol acetate regiochemistry.
