Coordination compounds of Group IB metals. II. Some tertiary phosphine and phosphite complexes of gold(I)

Abstract

Gold(1) complexes of type R₃AuX (R = Bu, Ph; X = Cl, Br, SCN), complexes Ph₃PAuSR (R = alkyl, aryl), Ph₃PAuEt, (PhO)₃PAuCl, and bis(phosphine) complexes of type [R₃PauPR₃]⁺X^- (R = Et, Ph; X = Cl, Br, SCN) are described. Triphenyl phosphite complexes were very unstable; attempts to prepare triethyl phosphite complexes were unsuccessful. A triethylphosphine complex of aurous sulphide, Et₃PauSAuPEt₃, and a sulphonium complex, [(Ph₃PAu)₃S]⁺Cl^-, were also prepared.
