Interaction of diazoimidazoles and their diazonium salts with primary and secondary amines

A number of 2- and 5-triazenoimidazoles were prepared by the coupling of diazo compounds with aliphatic amines; however, 4,5-dicyanoimidazole-2-diazonium chloride was transformed into 2-amino-1-methylimidazole-4,5-dicarbonitrile.
