The advantageous impact of a pentafluorosulfanyl substituent on the properties of furazan-containing energetic materials was demonstrated by the synthesis and study of the energetic properties of ten new compounds. The thermal stability of these compounds was evaluated by DSC and TGA, whereas densities, heats of formation, pressures of detonation and speeds of detonation were obtained computationally

A convenient preparation method was developed for 4″-nitro-3,3′:4′,3″-ter-1,2,5-oxadiazol-4-amine by substituting one nitro group of 4,4″-dinitro-3,3′:4′,3″-ter-1,2,5-oxadiazole at treating with equivalent quantity of ammonia in solvents of low polarity. In the reaction of the obtained amino-nitro derivative with N- and О- nucleophiles depending on the reaction conditions and the nucleophile nature

Abstract3,4-Bis(4-aminofurazan-3-yl)furazan was used to obtain a new energetic terfurazan derivative, namely, bis(4″-nitro[3,3’:4’,3″]terfurazan-4-yl)diazene, the sensitivity of which to mechainical impact was found to be close to that of HMX. The new compound was characterized by NMR spectroscopy, mass spectroscopy, IR spectroscopy, X-ray crystallography, and elemental analysis.
