The carbopalladation of the enolates of functi`onalized allenes 3 with a vinylic or arylic palladium complex leads with good yield to cyclic compounds 5 and (or) 6 resulting from the attack of the anion on each of the terminal carbon atoms of the intermediate π-allylic complex 4. The regioselectivity is mainly dependent on the nature of the entering vinylic group, the formation of a cyclopropane being observed only when vinyl bromide is used. Its seems to reflect an equilibrium between the syn and anti structures of the p-allyl palladium 4 resulting from the carbopalladatlon step.
