In this study, we present an investigation into various nickel phosphite and phosphite–phosphine complexes for use in the Mizoroki–Heck and Suzuki–Miyaura cross-coupling reactions and the ammonia arylation reaction. In these coupling reactions, it was discovered that the Ni[P(OEt)3]4, (dppf)Ni[P(OPh)3]2, and (binap)Ni[P(OPh)3]2 catalysts were the most effective. In addition, an optimisation process for these catalytic systems as well as functional group compatibility are discussed.
在本研究中,我们对用于 Mizoroki-Heck 和 Suzukii-Miyaura 交叉偶联反应以及氨芳基化反应的各种亚磷酸镍和亚磷酸膦配合物进行了研究。研究发现,在这些偶联反应中,Ni[P(OEt)3]4、(dppf)Ni[P(OPh)3]2 和 (binap)Ni[P(OPh)3]2 催化剂最为有效。此外,还讨论了这些催化体系的优化过程以及官能团的兼容性。
