摘要: A new family of energetic compounds, nitropyrazoles bearing a trinitromethyl moiety at the nitrogen atom heterocycle, was designed. The desirable high-energy dense oxidizers 3,4-dinitro- and 3,5-dinitro-1-(trinitromethyl)pyrazoles were synthesized in good yields by destructive nitration corresponding 1-acetonylpyrazoles. All prepared compounds fully characterized multinuclear NMR IR spectroscopy, as well elemental analysis. Single-crystal X-ray diffraction studies show remarkably high density. Impact sensitivity tests thermal stability measurements also performed. pyrazoles possess positive calculated heats formation exhibit promising performance that is range 1,3,5-trinitroperhydro-1,3,5-triazine pentaerythritol tetranitrate. oxygen balance are candidates for environmentally benign materials.
