ligand is reported. These reactions occur under low catalyst loading and in high yields and display wide scope, including the coupling of bulky thiols and trisubstituted bromoolefins, and functional group tolerance. In addition, the thioetherification of less reactive chloroalkenes and, for the first time, alkenyl tosylates was accomplished using a catalyst generated from CyPFtBu alkylbisphosphine ligand
据报道,链烯基
溴化物与
硫醇的交联反应是由廉价dppf
配体衍生的
钯配合物催化的。这些反应在低催化剂负载和高收率下发生,并显示出较宽的范围,包括大体积
硫醇和三取代
溴代烯烃的偶联以及官能团的耐受性。另外,使用由CyPF t Bu烷基双
膦配体产生的催化剂实现了反应性较低的
氯代烯烃的
硫醚化以及首次
