With the increase in demand for high-performance composite explosives, search advanced energetic melt-castable compounds has attracted increasing attention field of materials. Herein, two new materials with nitromethyl and azidomethyl substituents (1-(nitromethyl)-3,4-dinitro-1H-pyrazole (NMDNP) 1-(azidomethyl)-3,4-dinitro-1H-pyrazole (AMDNP) were prepared by substituent modification a potential molecule ((3,4-dinitro-1H-pyrazol-1-yl) methyl nitrate, MC-4), respectively. NMDNP exhibited suitable melting point (90 °C), good thermal stability (Td : 185 °C) excellent detonation performance (8484 m s-1 ) impact sensitivity (25 J), thereby demonstrating promise as an material. Simultaneously, compared nitrato-methyl substituents, greater advantages regulating performance.

Structural binary cleavage of 3,7-diamino-2,6-dinitro-1H,5H-pyrazolo-[1,2-a]pyrazole-1,5-dione 3, under nucleophilic conditions, leads to the formation a monocyclic pyrazole unit 5-amino-4-nitro-1,2-dihydro-3H-pyrazol-3-one, 4. Additionally, various salts ring were synthesized and fully characterized. Detonation properties mechanical sensitivities 4 other new compounds are remarkably improved compared 3. This simple efficient strategy is highly desirable for future studies on development insensitive high performing materials.
