[1,2,4]Triazolo[1,5-d][1,2,4]oxadiazole ring system - A novel building block for creating energetic compounds

Three neutral energetic compounds with a novel oxygen-containing fused ring were synthesized by starting from 4-amino-1,2,5-oxadiazole carbohydroximoyl chloride and 5-bromo-3-nitro-1-H-1,2,4-triazole, their structures fully characterized using multinuclear nuclear magnetic resonance (NMR) spectroscopy, infrared (IR), elemental analysis, and single crystal X-ray structuring. Their decomposition temperature, density and impact sensitivity were measured, their detonation performances were calculated by EXPLO5 v6.05.

Automated summary

Three neutral energetic compounds with a novel oxygen-containing fused ring were synthesized and fully characterized in this study. Their detonation performances were evaluated based on their decomposition temperature, density, and impact sensitivity.
