Perchlorylamino furazans and their salts: new high-energy-density materials with high sensitivity

The first perchlorylamino heterocycles, perchlorylaminofurazans, were obtained by the reaction of N-lithiated and N-silylated aminofurazans with FClO₃ or Cl₂O₇. Energetic salts comprising nitrogen-rich 1,2,4-triazolbased cations and 3-nitro-4-(perchlorylamino)furazan anion whose predicted explosive performance was close or superior to that of HMX were synthesized and characterized. Although the explosive output of perchlorylaminofurazan salts is better compared to relative nitraminofurazan ones, they would more readily degrade (explode!) upon impact, friction or heating.
