Palladium(0) complexes [Pd(PPh3)4 or Pd(dba)2], (dba = dibenzylideneacetone) in the presence of 1,4-bis(diphenylphosphino)butane, can catalyse the reaction of alkenes and formate esters to give linear carboxylic esters as the major product, while the branched chain isomer was the principal ester obtained by use of a palladium(II) complex [bis(triphenylphosphine)palladium dichloride] as the catalyst
钯(0)络合物[Pd(PPh 3)4或Pd(dba)2 ],(dba =二亚苄基丙酮),在1,4-双(二苯基膦基)丁烷的存在下,可以催化烯烃和甲酸酯的反应,得到线性羧酸酯是主要产物,而支链异构体是通过使用钯(II)配合物[双(三苯基膦)钯二氯化物]作为催化剂获得的主要酯。
