3,4‐Bis(1H‐5‐tetrazolyl)furoxan (H2BTF, 2) and its monoanionic salts that contain nitrogen‐rich cations were readily synthesized and fully characterized by multinuclear NMR (1H, 13C) and IR spectroscopy, differential scanning calorimetry (DSC), and elemental analyses. Hydrazinium (3) and 4‐amino‐1,2,4‐triazolium (7) salts crystallized in the monoclinic space group P2(1)/n and have calculated densities

Newenergetic monomers: A set of new (2-vinyltetrazolyl)furoxans as potential energetic monomers was prepared through the regioselective alkylation of the corresponding tetrazoles. Synthesized materials have good densities, high nitrogen-oxygen contents and high enthalpies of formation. A combination of these parameters resulted in good detonation performance of all studied (2-vinyltetrazolyl)furoxans

A general, highly effective two-step approach for direct synthesis of (1H-tetrazol-5-yl)furoxan ammonium salts with various functional substituents based on initial effective synthesis of cyanofuroxans by dehydration of furoxancarboxylic acid amides by the action of (CF3CO)(2)O/Py followed by [3+2]-cycloaddition of cyanofuroxans to ammonium azide, generated in situ from TMSN3 and NH4F, has been developed.
