Synthesis and characterization of alkylated trinitromethyl- and fluorodinitromethyl-tetrazoles

Here we report about the synthesis of 2-(2-nitro-2-azapropyl)-5-(trinitro-methyl)-tetrazole and analogue 2-(2-nitro-2-azapropyl)-5-(fluorodinitromethyl)-tetrazole. The prepared materials were characterized thoroughly including single crystal X-ray diffraction and differential scanning calorimetry measurements. The sensitivities towards impact, friction and electrostatic discharge were determined. In addition, the performance of the materials was calculated using the EXPLO5 computer code, with heats of formation calculated at the CBS-4M level of theory and densities obtained from pycnometer measurements.
