摘要：

Synthesis, characterisation and catalytic activity of a series of novel sigma,pi-dual gold(I) acetylide complexes are presented. sigma,pi-Dual gold(I) complexes based on the JohnPhos ligand or the bridging chiral MeO-BIPHEP ligand were generated from terminal alkynes in the presence of an organic base. The catalytic activity of the complexes was explored in a range of gold(I)-catalysed reactions of propargylic alcohol derivatives and their catalytic and enantioselective potentials were compared to corresponding monogold(I) phosphane and chiral digold(I) diphosphane species.
