sequence of nitration, fluorination, and difluoroamination reactions, providing the respective 2,2'-bis(trinitromethyl)-, 2,2'-bis(dinitro(fluoro)methyl)-, and 2,2'-bis[(N,N-difluoroamino)dinitromethyl] derivatives. The structures of all six products were studied by X-ray structural analysis; their crystal lattices were found to have high density (from 1.831 to 1.959 g/cm3 at 295 K). According to DTA
5,5'-二硝基双(1,2,4-三唑)和5,5'-二硝基双(1,2,3-三唑)的N,N'-二硝基甲基衍生物用于硝化,氟化和提供相应的2,2'-双(三硝基甲基)-,2,2'-双(二硝基(氟)甲基)-和2,2'-双[(N,N-二氟氨基)二硝基甲基]衍生物。通过X射线结构分析研究了全部六个产品的结构;发现它们的晶格具有高密度(在295 K下为1.831至1.959 g / cm 3)。根据DTA数据,这些化合物的初始分解温度为107至198℃。2,2'-二[二硝基(氟)甲基] -5,5'-二硝基-2- ħ,2' ħ-3,3'-bi(1,2,4-triazole)因其高密度(1.959 g / cm 3),良好的热稳定性(初始分解温度195)而对复合高能材料的设计很感兴趣。°С),以及原材料的可用性。
