Arylazo derivatives of 3,5-diamino-1,2-dithiolium bromides were obtained by oxidation of arylhydrazones of dithiomesoxalic acid diamides with bromine in chloroform; the nonquaternized amino group of the products reacts with aryl iso(thio)cyanates to give the corresponding ureas and thioureas, regardless of the conditions.
