Description
Summary:[Display omitted] •The reduction of AuCl4− by thiomalate in an aqueous solution was studied, the main products were determined.•The influence of pH and temperature was investigated.•It is shown that the rate of the process is strongly influenced by the concentration of chloride ions.•The use of cysteine or glutathione instead of thiomalate did not show qualitative differences in the nature of the process and products. The process of AuCl4− reduction by thiomalate (mercaptosuccinate, TM*,–OOCCH2CH(SH)COO−) at CAu = (2–10) × 10−4 M and CTM/CAu
