摘要:Regioselective control by a catalyst switch in palladium-catalyzed benzylallylation of arylethylidene malononitriles (alpha-benzyl-beta-allylation versus alpha-allyl-beta-benzylation) is described. The three-component reaction of 2-(bromomethyl)naphthalenes, arylethylidene malononitriles, and allyltributylstannane proceeds smoothly with palladium nanoparticles as a catalyst to provide a-benzyl-b-allylation products in good yields. The regioselectivity of the benzylallylation reaction is completely overturned with Pd(PPh3)(4) as the catalyst instead of palladium nanoparticles to obtain alpha-allyl-beta-benzylation products in moderate to good yields.
