Synthesis of pentafluorosulfanylpyrazole and pentafluorosulfanyl-1,2,3-triazole and their derivatives as energetic materials by click chemistry.
1-Pentafluorosulfanyl acetylene and its derivatives react with azide or diazomethane giving rise to an SF5-substituted 1,2,3-triazole or pyrazole. The SF5 group increases density remarkably and as a result enhances the detonation performance of the energetic materials relative to the CF3 group.
