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.
