Polycyclic <i>N</i>-oxides: high performing, low sensitivity energetic materials

Abstract

Polycyclic N-oxides were developed based on the heterocycles 1,2,4,5-tetrazine and 4H,8H-difurazano[3,4-b:3',4'-e]pyrazine. The new compounds are energetic and have excellent explosive properties, while maintaining low mechanical sensitivities. Most notably, compound 7 is thermally stable, insensitive, and has superior detonation properties to the state-of-the-art insensitive high explosive, 1,3,5-triamino-2,4,6-trinitrobenzene.
