1,2,3-triazolo [4,5-e] furazano [3,4-b] pyrazine-6-oxides (TNFPO) was synthesized via four steps of reactions by using 3, 4-diaminofurazan as starting material with the yield of 91.1%. The structure of TNFPO was determined by 1H NMR, 13C NMR, IR, MS as well as elemental analysis. The optimized results show that 100% HNO3/(CF3CO2)2=1:1.5 is the best reaction system and 20°C is the optimum temperature. The thermal performance of TNFPO was analyzed by DSC and TG techniques, and the synthetic mechanism of 1,2,3-triazole 2-oxides in the system of nitric acid/trifluoracetic anhydride was also discussed.
