A new zwitterionic Palladium (II) complex has been synthesized by the one-pot mixing of Pd(OAc)2, 2-aminophenol and (3-formyl-4-hydroxy-5-methylbenzyl) triphenylphosphonium chloride, in refluxing ethanol. The metal complex formed was characterized by 1H NMR, 13C NMR, 31P NMR and X-ray crystallographic technique and its efficiency tested as a homogeneous pre-catalyst in Heck-Mizoroki cross coupling
一种新的两性离子钯(II)络合物已经由一锅煮的Pd(OAC)的混合合成2,2-氨基苯酚和(3-甲酰基-4-羟基-5-甲基苄基)三苯基鏻氯化物,在回流的乙醇中。形成的金属配合物通过1 H NMR,13 C NMR,31 P NMR和X射线晶体学技术进行表征,并使用γ-戊内酯(GVL)作为Heck-Mizoroki交叉偶联反应的均相预催化剂,对其效率进行了测试。生物质衍生的绿色培养基。所有产品均以良好至极好的收率获得。
