A series of 1,3-bis(2-alkyltetrazol-5-yl)triazenes have been synthesized in high yields by treatment of sodium nitrite and hydrochloric acid with substituted-5-aminotetrazoles. All compounds were fully characterized using IR spectroscopy,~1H NMR and~(13) C NMR spectroscopy and high resolution mass spectrometer(HRMS). Most of these triazenes exhibit good detonation performance comparable with TNT and low melting points ranging from 81°C to 106°C, which are suitable for melt-cast explosives.Among these compounds, 1,3-bis(2-azidoethyltetrazol-5-yl)triazene(2g) displays a low melting point(106°C), moderate onset decomposition temperature(183°C) and good detonation performance(D:7087 m/s; P: 17.6 GPa).
