✦ Synopsis

Reaction of the aminophosphane ligands 2-(diphenylphosphanylamino)pyridine (Ph 2 PNHpy, 1) and 3-(diphenylphosphanylamino)-1,2,4-triazole [Ph 2 PNH(Htrz), 2] with the gold(I) compound [AuCl(tht)] (tht = tetrahydrothiophene) gave the complexes [AuCl(Ph 2 PNHpy)]

(3) and [AuCl{Ph 2 PNH(Htrz)}] (4), respectively. A series of new gold(I) thiolate derivatives were synthesized from the reactions of complex 3 or 4 with 1 equiv. of a deprotonated thiol ligand. Complexes [Au(SR)(PPh 2 NHpy)] (5-8) were prepared by reaction of complex 3 with the corresponding thiol HSR [HSR = 2-mercaptopyridine (2-HSpy), 2-mercaptonicotinic acid (2-H 2 -mna), 2-thiouracil (2-HTU) or 2-thiocytosine (2-HTC)] in the presence of sodium carbonate or triethylamine. Complexes [Au(SR){PPh 2 NH(Htrz)}] (9-11) were prepared by the treatment of complex 4 with triethylamine and the re-
