摘要
制备了纤维素氧瞵-钯配合物催化剂,详细考察了催化剂对三(正)丁基锡氢化物和酰卤化合物偶联反应的催化作用。结果表明,该负载型高分子配合物催化剂对偶联反应具有很高的催化活性和化学选择性,分离容易,可重复使用,用XPS方法对催化机理进行了研究。
The cellulose oxyphosphine palladium complex catalyst was prepared and the catalytic activity of catalyst in the cross - coupling reaction of tributyltin hydride with acid chlorides was investigated. The experimental results show that the supported catalyst has high catalytic activity and chemical selectivity, it can be separated easily from the reaction mixture after reaction and can be reused for several time.The catalytic mechanism also were discussed and studied by XPS.
