52409-22-0, Name is Pd2(DBA)3, belongs to catalyst-palladium compound, is a common compound. COA of Formula: C51H42O3Pd2In an article, once mentioned the new application about 52409-22-0.
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 alpha-benzyl-beta-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.
