Compounds containing dinitromethyl groups are ideal structural units for energetic materials due to their high density and good oxygen balance. However, these compounds often have drawbacks, such as low decomposition temperatures mechanical sensitivity, which limit practical applications in materials. In order address issues, a series of novel nitrogen- oxygen-rich 7–11 been successfully designed by incorporating amino enhance hydrogen bonding. Among them, compound 8 exhibited an excellent overall performance (Tdec = 215 °C, ρ 1.81 g cm–3, D 8603 m s–1, IS > 40 J, FS 360 N) displayed typical secondary explosive characteristics. During the synthesis process, new safe method was developed synthesize 3,4-di(nitramino)furazan its ion salts. The conversion from 1,2,4-oxadiazole 1,2,5-oxadiazole via rearrangement explored through multiple experiments investigate mechanism. This transformation is valuable complement azole–azole Boulton–Katritzky type.
