Investigations of bis(methyltetrazolyl)triazenes as nitrogen-rich ingredients in solid rocket propellants – Synthesis, characterization and properties

Methylation of Ylidene‐Triazenes: Insight and Guidance for 1,3‐Dipolar Cycloaddition Reactions

“…[36] Although no analogues to 4c have been reported in the literature to the best of our knowledge, there are related molecules that belong to the broader class of N 1 ,N 2 ,N 3 -trisubstituted triazenes. [38][39][40][41][42][43][44][45][46][47] Despite substantial variation in the chemical identity of the N-substituents, the bond lengths observed within the N 3 -R (where R is a variety of alkyl groups) fragments of these previously reported . Similarly, the N1-N2-N3 angle and N1-N2-N3-C3 torsion in 4c [113.6(2) and 2.6(2)°, respectively] were consistent with the corresponding angles observed in other trisubstituted triazene systems (111.3-114.6 and 0.1-4.0°, respectively).…”

[38][39][40][41][42][43][44][45][46][47] Interestingly, the fact that these structural features are so highly conserved suggested to us that the bonding within N 1 ,N 3 ,N 3 -trisubstituted triazenes is determined primarily by the N 3 -CH 3 fragment and largely independent of the chemical identity of the other N-substituents.…”

Tetrazole Azasydnone (C2N7O2H) And Its Salts: High‐Performing Zwitterionic Energetic Materials Containing A Unique Explosophore

“…High-nitrogen heterocyclesm ake up the backboneo fm any energetic materials. [6][7][8] Heterocycles such as tetrazoles, [9,10] tetrazines, [11][12][13][14] triazoles [15][16][17] and triazines [18,19] have all found extensiveu se in the design of new energetic materials. Their nitrogen contentc ontributes to the energetic properties of [a] M. L. Gettings these materials due to high heats of formation as ar esult of the thermodynamic driving force of nitrogenous compounds towardst he formation of nitrogen gas.…”

Contributions to the Chemistry ofN‐Methylnitramine: Crystal Structure, Synthesis of Nitrogen‐Rich Salts, and Reactions towards 2‐Nitro‐2‐azapropyl Derivatives

“…The test was performed in a glass test vessel at atmospheric pressure with 312 mg of 1 . It was previously shown that tempering a substance for 48 h at 40 °C below its decomposition temperature results in storage periods over approximately 50 years at room temperature 39. A temperature below the boiling point of 1 was chosen and elemental analysis before the test and after 48 h was carried out.…”
