摘要：

Two novel gold(I) complexes with a phosphoguanidine ligand and with a novel cationic phosphane ligand have been prepared and structurally characterized. The phosphoguanidine ligand supports oxidative addition of biphenylene to the gold(I) centre, though the yield of the reaction is low. The phopshoguanidine gold(I) complexes is also able to efficiently catalyze the hydroamination of phenylacetylene with mesitylamine, whereas the gold(I) complex with the cationic phosphane ligand, due to its more electron-poor character, promotes the hydroarylation of ethyl propiolate with mesitylene.
