The reaction of 4-aminobenzofurazan with aryldiazonium salts leads to the formation of 4-amino-5-arylazobenzofurazans and 5-amino-2-aryl-4-nitroso-2H-benzotriazoles, products of the rearrangement of the initially formed 4-amino-7-(arylazo)benzofurans.Oxidation of the benzofurazan as well as of the triazole derivatives gives 7-aryl-1,2,3-triazolo<4,5-e>benzofuranzas.The chemical properties of some of the compounds obtained have been investigated.
