Abstract
Furazan derivatives have been pursued as attractive building blocks for advanced energetic materials; however, their low thermal stability limits their practical application. Two synthetic strategies, including diazotization–cyclization and oxidative amine coupling, were employed to synthesize a series of furazan compounds with good thermal stability. Among these, ( E )-1,2-bis(5-(4-nitro-1,2,5-oxadiazol-3-yl)-1 H -1,2,4-triazol-3-yl) diazene ( 10 ) achieves a good balance between detonation performance ( D v = 8802 m s –1; P = 32.56 GPa) and thermal stability ( T d = 295 °C), surpassing that of RDX. This work provides comprehensive guidance for synthesizing energetic materials with high detonation performance and excellent thermal stability.
