Реферат: The synthesis of novel energetic compounds for the development of propellants and powders with significantly improved characteristics is an important and complex task. The combination of little- studied hydrogen-containing explosophoric groups and high nitrogen heterocycles is a powerful strategy for creating the compounds needed to address this challenge. A number of energetic substituted furazans, bearing a rare 1,3-dinitro-1,3-diazabutyl group, were synthesized and their properties were thoroughly studied. The resulting (1,3-dinitro-1,3-diazabutyl)furazans 1b–f have good thermal stability (onset decomposition temperatures 124–160 °C), high experimental enthalpies of formation (947–1528 kJ/kg) and acceptable densities (1.60–1.70 g/cm3). In terms of detonation performance, all synthesized compounds (detonation velocities D = 8.0–8.3 km/s, detonation pressures PC–J = 27–30 GPa) are comparable with pentaerythritol tetranitrate (PETN) (D = 8.3 km/s, PC–J = 31 GPa). For novel compounds "structure-property" relationships have been revealed that will allow predicting the key energetic characteristics of hypothetical compounds containing 1,3-dinitro-1,3-diazabutyl explosophoric group.
