Catalytic effect of metal ions on the reaction of p-toluenediazonium sulfate and thiocyanate ion was examined with p-tolyl thiocyanate produced using gas-liquid chromatography. The catalytic actiono f bivalent and trivalent iron ions was apparently more effective than that of univalent copper. From these reactions, double complexes of p-toluenediazonium ion with metal thiocyanate of general formula [chemical formula] were isolated. These substances rapidly decomposed when heated above their mp, yielding p-tolyl thiocyanate, which is the same compound obtained by the reaction of the solution of diazonium salts with metal thiocyanates. This is a strong evidence that these double complexes were actually formed in the Sandmeyer reaction.
