Reactions of 2,4-Disubstituted 5-Nitro-1,2,3-triazole 1-Oxides. 4. Dealkylation of 2-Substituted 4,5-Dinitro-1,2,3-triazole 1-Oxides

The N-dealkylation of 2-alkyl or 2-benzyl-substituted 4,5-dinitro-1,2,3-triazole 1-oxides has been studied. Conditions have been found for N-de-tert-butylation and 4-amino-5-nitro-1,2,3-triazole 1-oxide has been synthesized for the first time.
