Synthesis, characterisation and catalytic activity of a series of novel σ,π‐dual gold(I) acetylide complexes are presented. σ,π‐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.
