Abstract
A novel and green energetic compound, 2-oxo-5-nitro-3-(5-nitroimino-1,3,4-oxadiazole-2-yl)-pyrazine, was designed and prepared in this study. It was identified and characterized using X-ray single-crystal diffraction, IR spectroscopy, NMR spectroscopy, mass spectrometry, differential scanning calorimetry, and elemental analysis. The newly developed compound is an insensitive booster explosive with a high detonation velocity (D = 8516 m s−1), highs detonation pressure (P = 31.85 GPa), low mechanical sensitivities (impact sensitivity: 32 J, friction sensitivity: > 360 N), and excellent thermal stability (decomposition temperature: 270 °C). This compound and further studies will greatly boost the application of green energetic materials with improved performance.
