“…In the last decade, most advanced energetic materials have been based on five-membered nitrogen-rich heterocyclic systems (azoles). [25][26][27][28][29][30][31] Among azoles, pyrazole-based energetic compounds are particularly in demand due to their stability and easy derivatization at the three carbon atoms in the ring. [32][33][34][35][36] 4-Substituted-3,5-dinitropyrazoles with various substituents at the 4 th position (e.g., -NH 2 , -NO 2 , -N 3 , -NNO 2 , etc.)…”
