Abstract

Organic sulphauro compounds are prepared by reacting a mercapto compound R-SH with aurous cyanide or an alkali aurocyanide. R p may be a substituted or unsubstituted alkyl or aryl radical. In examples (1) an aqueous solution of thiomalic acid is added to an aqueous suspension of aurous cyanide and heated on the steam bath. The product is evaporated and triturated with hot ethyl acetate to give pure auro-thiomalic acid. (2) A solution of gold chloride is added to a solution of sodium bisulphite, potassium hydroxide and potassium cyanide in water and the product added to cysteine hydrochloride to give aurocysteine. (3) An aqueous suspension of aurous cyanide is added to p-acetamino-thiophenol to give p-sulphauro-acetanilide. (4) An alcoholic solution of cetyl mercaptan is treated with active aurous cyanide to form cetyl auromercaptan. The aurous cyanide is prepared in a form suitable for use in the present invention by pouring one mol of reagent gold chloride slowly with stirring into a solution prepared by dissolving 4 mols. sodium hydroxide, one mol. sodium bisulphite and two mols. sodium cyanide in the above order. The mixture is heated on the steam for 1/2 hour and then an equal volume of concentrated hydrochloric acid added. Heating is continued for one hour to form a yellow precipitate of aurous cyanide.
