N2 - The new general synthetic method has been developed for the convenient preparation of ami-nonitrofurazans. The synthesis of 3-amino-4-nitrofurazan (ANF), 3-amino-3′-nitro-4, 4′-azoxyfurazan (ANAF) and 3-amino-3′-nitro-4, 4′-azofurazan (ANAzF) were achieved by oxidizing 3, 4-diaminofurazan (DAF), 3, 3′-diamino-4, 4′-azoxyfurazan (DAAF) and 3, 3′-diamino-4, 4′-azofurazan (DAAzF) respectively, with the oxidizing mixtures of hydrogen peroxide, sodium tungstate or ammonium persulfate and methane-sulfonic acid [H 2O 2/CH 3SO 3H/Na 2WO 4 or (NH 4) 2S 2O 8] with reduced acidity to give above 65% yield of ANF and ANAF, and 15% yield of ANAzF. The experiments showed that the mixture of H 2O 2 and Na 2WO 4 or (NH 4) 2S 2O 8) in CH 3SO 3H media is a new kind of efficient oxidant for the synthesis of one or more furazan rings with amino and nitro groups.
