Evolving the Scope of 5,5’?Azobistetrazoles in the Search for High Performing Green Energetic Materials

The azotetrazole moiety represents a great platform for energetic materials, it offers planar and nitrogen-rich backbone, combined with high heat of formation, which easily can be functionalized tuned. Herein, we start from sodium 5-aminotetrazolate obtain two isomers by substitution reaction 2-chloroethanol. Azidoethyl nitratoethyl substituted azo- tetrazoles were finally synthesized oxidative azo coupling the respective N-ethyl 5-aminotetrazole precursors using tert-butyl hypochlorite as reagent. All compounds analyzed through multicore NMR IR spectroscopy well mass spectrometry. solid further investigated low-temperature X-ray crystallography. purity was verified CHNO elemental analysis decomposition temperature (DTA) sensitivities toward impact, friction electrostatic discharged determined. Based on CBS-4M calculation results, properties calculated EXPLO5 code.
