| Abstract: | Six novel energetic furazans containing tetrazol-5-yl-NNO-azoxy moiety were synthesized using (cyano-NNO-azoxy)-furazans as starting compounds. The obtained compounds exhibit high enthalpies of formation (531–792 kcal kg–1), acceptable densities (1.70–1.76 g cm–3), good thermal stability (Tonset = 146–199 °C), and, as a result, excellent detonation performance (detonation velocities of 8.61–8.95 km s?1 and detonation pressures of 31.6–36.0 GPa). |
