Abstract A mild procedure for the preparation of 2-(5-amino-1-aryl-1H-1, 2, 3-triazol-4-yl)-2- iminoacetonitriles and 2-(5-amino-1-aryl-1H-1, 2, 3-triazol-4-yl)-2-oxoacetonitriles was achieved by the reaction of diaminomaleonitrile and phenyl/substituted phenyl diazonium chlorides. 4-Nitrophenyl diazonium chloride afforded 2-amino-3-(3-(4-nitrophenyl) triaz-1-en- 1-yl) maleonitrile. Triazole iminoacetonitrile and maleonitrile derivatives were reacted ...
