Abstract A series of 1,3-bis(2-alkyltetrazol-5-yl)triazenes have been synthesized in high yields by treatment of sodium nitrite and hydrochloric acid with substituted-5-aminotetrazoles. All compounds were fully characterized using IR spectroscopy, 1 H NMR and 13 C NMR spectroscopy and high resolution mass spectrometer (HRMS). Most of these triazenes exhibit good detonation performance comparable with

5-R-Substituted 1(2)-vinyltetrazoles (R = Ar, Alk, CH2=CH, NH2, H) were synthesized by alkylation of 5-R-tetrazoles with 1,2-dibromoethane in the presence of triethylamine in acetonitrile, followed by elimination of triethylamine hydrobromide. Vinylation of dinuclear substrates, such as bis(1H-tetrazol-5-yl)methane and 1,3-bis(1H-tetrazol-5-yl)benzene, under analogous conditions gave the corresponding N-1, N-2'- and N-2,N-2'-divinyl derivatives.
Pentazadiene: a high-nitrogen linkage in energetic materials

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
