✦ Synopsis

A novel class of energetic materials, N-di¯uoroaminonitroazoles was synthesized. One molecule of these compounds contains simultaneously a nitro group and di¯uoroamine one. A method of synthesizing N-di¯uoroaminonitroazoles incorporates the interaction of N-unsubstituted nitroazoles with O-¯uorosulfonyl-N,N-di¯uorohydroxylamine (F 2 NOSO 2 F) in the presence of bases.

To estimate possible prospects of these compounds, energy content, molecular crystal density, some parameters of detonation and combustion were calculated using some well-known methods of computational chemistry, as well as some of our original schemes. In addition, thermostability (by the DTA method) and density were identi®ed experimentally for a cross-section row of the studied compounds. The reasons for relatively low stability of this type of substances were given.
