Two mechanistic features of the palladium-catalyzed allylic alkylation reaction of dienyl acetatesvinyl (π-allyl)palladium intermediate equilibration and palladium-catalyzed ionization of the bisallylic malonate productsaccount for the observed product ratios and nucleophile counterion effects. Three hexadienyl acetate substrates, isomeric with respect to the location of the leaving group to the dienyl
