    摘要: The known preparation of gold(I) mercaptides by means of reacting a gold(I) halogenide dialkyl sulfide complex, obtainable from a gold(III) halogenide or gold(III) halogen complex and a sulfide, with a mercaptan can be improved if a (C.sub.1 - to C.sub.8 -)-alkyl mercapto-(C.sub.3 - to C.sub.6 -) amino acid or a water-soluble salt thereof is used as organic sulfide. The advantages of the sulfides of the invention over the previously used sulfides reside in their water solubility and insolubility in solvents and therewith in a simplification of the purification of gold(I) mercaptides independently of their structure and solubility. A further advantage of alkyl mercapto amino acids, especially D,L methionine, is their odor, which is much less than that of the (C.sub.1 -C.sub.8) alkyl sulfides previously used.
