3-Amino-4-nitrofurazan (ANF) and its derivatives are a new kind of important energetic materials. ANF was synthesized in three steps. The first two steps involved the synthesis of diaminoglyoxime (DAG) from aqueous glyoxal and hydroxylamine and 3,4-diaminofurazan (DAF) from DAG dehydration. Then DAF was oxidized using the mixture of hydrogen peroxide, sodium tungstate and methanesulfonic acid (H2O2/CH3SO3H/Na2WO4) in place of the mixture of hydrogen peroxide, ammonium persulfate and sulfuric acid [H2O2/H2SO4/(NH4)2S2O8] to give a 67% yield of ANF. Treatment of ANF with potassium permanga-nate and concentrated hydrochloric acid afforded 3,3’-dinitro-4,4’-azofurazan (DNAzF) in a 54.7% yield. The experiments showed that the mixture of H2O2/CH3SO3H/Na2WO4 was a new kind of efficient oxidant for the synthesis of mono- or multi-furazan rings with amino and nitro groups.
