Energetic material is a very essential company of compounds, widely used in various fields, primarily the military industry and space technologies. These compounds are unique that they capable instantly decomposing to release enormous energy. The chemical diversity energetic organic constantly increasing through combination high-nitrogen frameworks explosophoric groups, which follows overall trend interest their chemistry applications. scientific community looking for more powerful less sensitive external impulses both civilian use. Herein, detailed overview regarding classic novel groups frameworks, as well description selected synthesis target has been given time period since 2010. physical properties performances benchmark prospective also collected.

The mechanism of thermal decomposition 1-tert-butyl-2-methoxydiazene-1-oxide and 1-ethyl-2-methoxydiazene-1-oxide was investigated by quantum chemistry methods at the CCSD/aug-cc-pVDZ level. It shown that thermolysis both compounds occurs same – hydrogen atom transfer from CH3 ethyl or tert-butyl group to N-oxide oxygen via a five-membered cyclic transition state in limiting stage. More precise calculations DLPNO-CCSD(T)/aug-cc-pVTZ level were performed for this reaction channel. activation enthalpy all calculation levels channel is 150-170 kJ/mol, which corresponds experimental data. products composition completely coincides with calculated one.

Novel energetic furazans 3a–3c and 4a–4c containing isomeric (3,4-dinitro-1H-pyrazol-1-yl)-NNO-azoxy (3,5-dinitro-1H-pyrazol-1-yl)-NNO-azoxy moieties have been obtained. A synthetic approach to aminofurazans 3a 4a involves the reaction of 1-amino-3,4-dinitro-1H-pyrazole or 1-amino-3,5-dinitro-1H-pyrazole with 2,2,2-trifluoro-N-(4-nitrosofurazan-3-yl)acetamide dibromoisocyanuric acid, followed by removal trifluoroacetyl group. Transformations amino group in gave corresponding nitro (3b, 4b) azo (3c, 4c) substituted furazans. The compounds synthesized exhibit high experimental enthalpies formation (2093–2847 kJ·kg−1), good thermal stabilities (onset decomposition temperatures 203–228 °C), acceptable densities (1.78–1.87 g·cm−3) detonation parameters (detonation velocities D = 8.71–8.99 km s−1, pressures p 33.9–38.7 GPa). Nitro 3b, 4b 3c, 4c evaluated as effective fillers for solid composite propellants, providing specific impulse values 9–11 s higher than similar formulations based on RDX HMX, 4–6 CL-20.
