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

synthesized via Ireland-Claisen rearrangements. The formation of intermediate (E)- and (Z)-enolates as the key-step was confirmed by NMR spectroscopy, which also indicated that only the (Z)-enolates rearrange, while the (E)-enolates are stable under the reaction conditions and hydrolyze back to the starting allylic esters during aqueous workup. As a consequence an incomplete rearrangement of the starting

Mukaiyama aldolreaction. The transformations proceeded with high diastereoselectivity. In case of benzaldehydes with electron-withdrawing substituents in the para-position, syn-α-SF5-β-hydroxyalkanoic acid esters were produced. The reaction was also successful with meta-substituted benzaldehydes and o-fluorobenzaldehyde. In contrast, p-methyl-, p-methoxy-, and p-ethoxybenzaldehydes led selectively to aldol

1,3,4-Oxadiazoles containing a combination of SF5-perfluoroalkyl, SF5-alkyl, polynitroalkyl and perfluoroalkyl substituents have been synthesized by cyclization (dehydration) of the corresponding diacyl hydrazines. The properties of oxadiazoles with SF5-perfluoroalkyl substituents are compared with those of similar oxadiazoles containing the corresponding perfluoroalkyl substituent (CF3 in place of SF5).
