Progress of our group and the other groups’ recent work in the field of palladium-catalyzed coupling reactions using amine as the ancillary ligands is summarized. The coupling reactions using the combination of palladium and amines as the catalytic system include the Suzuki-Miyaura cross-coupling reaction, Sonogashira cross-coupling reaction, Stille cross-coupling reaction, Hiyama cross-coupling reaction and Heck reaction. The results show that amine could be used as the inexpensive and highly efficient ligands to promote the palladium-catalyzed coupling reactions.
