The necessity of novel improved ingredients for peculiar applications like powders and propellants is boosting the research of energetic materials to replace conventional components. This work deals with the design, synthesis and complete characterization of novel energetic furazans 1a–e containing little-studied explosophoric 5-azido-1,3-dinitro-1,3-diazapentyl moiety
[–N(NO2)CH2N(NO2)CH2CH2N3]. The simple and concise method for the synthesis of these compounds has been developed on the basis of easily available aminofurazan derivatives. The compounds obtained have good thermal stability (onset decomposition temperatures 115–157 °C), high enthalpies of formation (1459–1914 kJ/kg) and acceptable densities (1.64–1.73 g/cm3). In terms of detonation performance, all synthesized compounds (detonation velocities D = 8.1–8.3 km/s, detonation pressures PC–J = 28–31 GPa) are comparable with pentaerythritol tetranitrate (PETN) (D = 8.3 km/s, PC–J = 31 GPa). Compounds 1a, 1d and 1e, comprising two 5-azido-1,3-dinitro-1,3-diazapentyl units and furazan backbones, due to its physicochemical, energetic and operational properties, are prototypes of an effective energetic filler for future high-performance propellants and powders.
