从[1-(2-二苯基膦-二茂铁基)-乙基]-二甲基胺出发,制备出3-[1-(2-二苯基膦-二茂铁基)-乙基]-1-甲基-3H-咪唑鎓碘盐(Ⅲ),总收率为75%;通过1H NMR和31P NMR对配体Ⅲ的结构进行了表征;研究了Pd(OAc)2/配体Ⅲ体系催化Suzuki-Miyaura偶联反应的活性及反应机理。
Starting from [1- (2-diphenylphosphino-ferrocenyl) -ethyl] -dimethylamine, 3- [1- (2-diphenylphosphino-ferrocenyl) -ethyl Yl] -1-methyl-3H-imidazolium iodonium salt (Ⅲ), the overall yield was 75%. The structure of ligand III was characterized by 1H NMR and 31P NMR. The effects of Pd (OAc) The activity and reaction mechanism of the Suzuki-Miyaura coupling reaction catalyzed by system Ⅲ.
