A mild and efficient strategy for the nitration of amino-substituted pyrazoles/triazole employing a mixture potassium nitrate concentrated sulfuric acid (KNO3/H2SO4) as nitrating reagent proceeded smoothly to give nitramino-substituted products. These were treated with corresponding bases energetic salts 1–10. The compounds fully characterized, single crystal X-ray diffraction studies obtained 1, 4, 6, 10. physical properties detonation performance measured or calculated. Salts 2, 8, 9 exhibited excellent acceptable sensitivities well good stabilities, which suggested that they have potential be useful high-performance explosives.
