Gold and Silver Complexes with the Ligands N-[Bis(isopropoxy)-thiophosphoryl]thiobenzamide and N-[Bis(isopropoxy)thiophosphoryl]-N′-phenylthiourea

Abstract

Gold and silver complexes with the N-[bis(isopropoxy)-thiophosphoryl]thiobenzamide (HL1) and N-[bis(isopropoxy)-thiophosphoryl]-N′-phenylthiourea (HL2) ligands are reported, The compounds [M(HL)(PPh3)]TfO, [Ag(HL)(TfO)] and [Ag(HL)(PPh3)2]TfO were obtained by the reaction of both ligands with the corresponding trifluoromethanesulfonate salts. The (acetylacetonato)gold and -silver materials [M(acac)(PPh3)] or [Au(acac)(C6F5)2] cause deprotonation of the ligands and afford [ML(PPh3)] or [AuL(C6F 5)2], whereas the reaction of [Au(TfO)(PPh3)] with HL1 in a 2:1 molar ratio in KOH/MeOH affords [Au 2(L1)(PPh3)2]TfO, The first homoleptic anionic metal compounds [AuIL2]- are also reported. © Wiley-VCH Verlag GmbH & Co.
