ABSTRACT:
A synthesis of gold (I) cyanide is described which exhibits high yields and does not yield toxic gases (e.g., HCN). Gold (I) cyanide is important as a source of gold for gold plating baths. A synthesis of AuCN that does not involve evolution of toxic gases (e.g., HCN) is highly advantageous because no disposal problem is involved and the procedure is simpler and more straightforward.
