The peculiarities of the nitration reaction under acidic conditions were studied for a series of alkylamino-1,2,4,5-tetrazines. It was found that the extent of N,N'-dialkyl-1,2,4,5-tetrazine-3,6-diamine nitration was determined by the concentration of nitric acid and the selection of alkyl substituents at the exocyclic nitrogen atom. A new method was developed for the preparation of unsymmetrically substituted N,N'-dialkyl-1,2,4,5-tetrazine-3,6-diamines from N-nitro derivatives of N-alkyl-1,2,4,5-tetrazin-3-amines.
