HFOX-1-Amino-1-hydrazino-2,2-Dinitroethylene as a Precursor to Trifluoromethyl, Dinitro, or Trinitro-Based Energetic 1,2,4-Triazoles.

The chemical reactivity of 1-amino-1-hydrazino-2,2-dinitroethylene with a carboxylic acid for the construction of structurally interesting energetic triazoles and their energetic salts is reported. All new compounds were fully characterized by elemental analysis, infrared spectroscopy, nuclear magnetic resonance spectroscopy, and differential scanning calorimetry. Crystal analysis, good detonation properties, and low sensitivities of these trifluoromethyl and dinitro- or trinitro-based triazoles suggest their role as potential candidates for insensitive high-energy-density materials.
