The cross-coupling reaction of aryl chlorides with aliphatic and aromatic thiols catalyzed by palladium complexes of the strongly binding bisphosphine CyPF-tBu ligand (1) is reported. Most of the reactions catalyzed by complexes of ligand 1 occur with turnover numbers that exceed those of previous catalysts by two orders of magnitude. The reactions occur with excellent yields, broad scope and high
据报道,芳基氯化物与强结合双膦CyPF-tBu配体(1)的钯配合物催化的脂族和芳族硫醇的交叉偶联反应。由配体1的配合物催化的大多数反应发生的周转数比先前催化剂的周转数高两个数量级。反应以优异的收率,广泛的范围和对官能团的高耐受性进行。还描述了在低负载量下衍生自其他Josiphos型配体以及其他结构类型的配体的芳基卤化物与硫醇的偶联。
