Synthesis, structure, and alkylation of 4-nitroamino-1,2,4-triazole
Nitration of 4-amino-1,2,4-triazole with nitric acid in acetic anhydride gives the corresponding N-nitroamino derivative which has an inner salt structure. Its alkylation with alkyl halides, as well as with oxiranes, occurs only at the endocyclic nitrogen
