Abstract

Novel substituted benzenethiols can be easily prepared via aryl thiocyanates or aryl bromides. Reaction of [(Ph3P)AuCl] with the sterically-nondemanding benzenethiols HSC6H4NMe2-p and HSC6H4NMe3+-p and with the sterically-demanding benzenethiols HSCMe2H2NMe2-p, HSC6Me4H-p and in the presence of triethylamine yields the monomeric gold(I) complexes [(Ph3P)Au(SAr)], which are analogous to the gold-based antiarthritic drug Auranofin. Reaction with the sterically demanding dithiol HSC6Me4SH-p in the presence of NEt3 yields the dimeric complex [{(Ph3P)Au}2(μ-SC6Me4S-p)]. Spectrochemical and electrochemical data are reported. The crystal structures of [(Ph3P)Au(SC6H4NMe2-p)] and [(Ph3P)Au(SC6H4NMe3-p)]PF 6 have been solved: both complexes are monomeric in the solid state, lacking the short gold-gold interaction which is commonly found in gold(I) complexes of soft ligands, e.g., [(Ph3P)Au(SPh)]2.
