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

Abstract

Gold(1) complexes of type RsAuX (R = Bu, Ph; X = C1, Br, SCN), complexes PhsPAuSR (R = alkyl, aryl), PhsPAuEt, (PhO)sPAuCl, and bis(phosphine) complexes of type [R3PAuPRs]fX-(R = Et, Ph; X = C1, Br, SCN) are described. Triphenyl phosphite complexes were very unstable; attempts to prepare triethyl phosphite complexes were unsuccessful. A triethylphosphine complex of aurous sulphide, EtsPAuSAuPEts, and a sulphonium complex, [(Ph3PAu)3S]+C1-, were also prepared.

Gold(I) Complexes of Secondary and Tertiary Amines. Crystal Structure of Triphenylphosphineaurio(I)qinuclidinium Tetrafluoroborate

“…Quinuclidine was used as sup plied, and stored under anhydrous conditions. Triphenylphosphinegold(I) chloride was prepared by the published m ethod [28]. IR spectroscopic meas urements were carried out on a Nicolet 5-DX FT-IR spectrometer (KBr discs).…”

Sulfur Atoms as Ligands in Metal Complexes

“…Thus, compounds such as sulfanes of type (7) and sulfides of type (8) are hardly known in transition-metal chemistry, although they are normal in the main-group chemistry of sulfur. 71 ( 8 ) They are found almost exclusively with d'O-and dometalst61; two proven examples are (9)[lsl and…”
