hydroxylammonium salt (5), all the remaining salts exhibit good thermal stabilities with decomposition temperature above 180 °C. Furthermore, the densities of salts ranged from 1.65 g cm−3 to 1.88 g cm−3. Theoretical calculations provided detonation pressures and velocities for the energetic salts within the range of 24.9–38.0 GPa and 7582.2–9072.7 m s−1, respectively.

Energetic compounds that incorporate multiple nitrogen‐rich heterocycles are of great interest for high‐density energeticmaterials. A facile synthetic strategy to combine an oxy bridge and furazan groups, as well as tetrazole‐ols, into a molecule (5) was found. Some energetic salts based on 5 were prepared by neutralization. All of the compounds were fully characterized. Additionally, the structure

The reactions of 4,4'-dinitrodifurazanyl ether 1 with Na salts of hydroxyfurazans 2a-e were studied. The nitrofurazanyl fragment is replaced by the more nucleophilic R-furazanyl group; the observed transetherification affords unsymmetrical derivatives of difurazanyl ether. The ratio of the rate constants for the successive reaction steps was determined.
