Abstract

Abstract The palladium (o) catalyzed reaction of sodium ethylmalonate with α-allenic acetates and α-allenic phosphates leads exclusively to β-allenic malonates. The uncatalyzed reaction of Grignard reagents with the same phosphates gives 1, 3-dienes regiospecifically and with high stereoselectivity.
