The new general synthetic method has been developed for the convenient preparation of aminonitrofurazans. 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 methanesulfonic acid [H2O2/CH3SO3H/Na2WO4 or (NH4)2S2O8] with reduced acidity to give above 65% yield of ANF and ANAF, and 15% yield of ANAzF. The experiments showed that the mixture of H2O2 and Na2WO4 or (NH4)2S2O8) in CH3SO3H media is a new kind of efficient oxidant for the synthesis of one or more furazan rings with amino and nitro groups.

Key words: synthesis, aminofurazan, aminonitrofurazan, energetic material
