Abstract

The preparation of gold(I) mercaptides, which is known per se, by reaction of a gold(I) halide-dialkyl sulphide complex, which is obtainable from gold(III) halide or gold(III) halogen complex and a dialkyl sulphide, with a mercaptan can be improved if a (C1- to C8-)-alkylmercapto-(C3- to -C6-)amino acid or a water-soluble salt thereof is used as the dialkyl sulphide. The advantages of the dialkyl sulphides according to the invention compared with the dialkyl sulphides employed hitherto lies in their water-solubility and insolubility in organic solvents and thus a simplification of the purification of the gold(I) mercaptides, irrespective of their structure and solubility. A further advantage of the alkylmercaptoamino acids, D,L-methionine being particularly preferred, is their much lesser odour compared to the di(C1-C8)alkyl sulphides previously preferably used.
