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 13C 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).
