4,5-Bisnitratomethyl and Similar Representatives of the Rare Class of 2-Nitro-1,2,3-triazoles

A [3+2]-cycloaddition toward bishydroxymethyl-1,2,3-triazole makes the title compound available through selective nitration. The obtained sensitive 2-nitrotriazole was shown to have a high density of 1.764 g cm^-3 and a detonation velocity of 8590 m s^-1. It can also be classified as an oxidizer with an oxygen balance toward CO of 12%. Further representatives of this rare class of 2-nitro-1,2,3-triazoles were synthesized. One- and two-dimensional ¹⁵N NMR spectroscopy, crystal structure, and elemental analysis were performed.
