Embodiment 1

[0019] At a temperature of 25°C, 7H-bisfurazolo[3,4-b:3',4'-f]furazolo[3",4"-d]azepine (0.47g , 2mmol) and 1-chloro-2,4,6-trinitrobenzene (0.495g, 2mmol) were added into anhydrous acetonitrile (5mL), stirred and dissolved. Slowly add NEt dropwise to it 3 (0.404g, 4mmol), continue to stir the reaction for 4h. After the reaction was completed, the solvent was evaporated to dryness, and the resulting crude product was rinsed with absolute ethanol to obtain brown powder 7-(2,4,6-trinitrophenyl)bisfurazanofurazanazepine 0.70g, yield 78.5%, purity 98.6%.

Description

technical field [0001] The invention relates to a 7-(2,4,6-trinitrophenyl)bisfurazanofurazanoazepine compound, which belongs to the field of energetic materials. Background technique [0002] High energy density materials are widely used in explosives, propellants and pyrotechnics. Most of the high energy density materials designed with furazan ring as the matrix have the advantages of high energy density, high standard enthalpy of formation, and low mechanical sensitivity. Bisfurazanofurazanoazepine is a new type of energetic material, which has the advantages of high density and low sensitivity, but its further application is restricted due to the acidic imino group in its molecular structure. . Combining the polynitro-substituted aryl group with the parent ring of bisfurazanofurazanazepine can not only solve the acidity problem of the compound, improve its thermal stability, but also further increase the energy level . For example, "Synthesis and Characterization of B...
