    • In the presence of GSH, the ligand displacement reactions may take place to produce gold glutathione complex Au(SG)2-.3c It has been reported that thiourea can replace both the triethylphosphine (PEt 3) and thioglucose (SATg, moieties from AUR. The eliminated triethylphosphine may be converted to the corresponding triethylphosphine oxide.14a A similar ligand displacement reaction was observed when DTT was added to the gold selenolate complex. However, when PhSH was present, the phosphine displacement reaction was found to be extremely slow. For example, the 31P NMR signal observed for Ph3PAuCl at 33.3 ppm in CDC13 was unchanged upon the addition of even a large excess (10 equiv) of PhSH. Similar results were obtained when the experiments were carried out in MeOH. Furthermore, the phosphine ligand displacement by PhSH was not observed after the formation of gold selenolate complexes 11-13, suggesting

Furthermore, the phosphine ligand displacement by PhSH was not observed after the formation of gold selenolate complexes (11-13), suggesting that the gold selenolate complexes having a Se-Au-P moiety can be obtained in the presence of thiols.
