Reactions of 3-nitro-1,2,4-triazole derivatives with alkylating agents. 5. Selective synthesis of 1,4-dialkyl-and 1,4,5-trialkyl-3-nitro-1,2,4-triazolium salts from 1-alkyl-and 4,5-dialkyl-3-nitro-1,2,4-triazoles and dialkyl sulfates

Interaction of N(1)-alkyl-substituted 3-nitro-5-R-1,2,4- triazoles with dialkyl sulphates proceeds selectively and results in the respective salts of 1,4-dialkyl-, 1,4,5-trialkyl-3-nitro-1,2,4-triazoliums. The reaction of N(4)-alkyl-substituted 3-nitro-5-R-1,2,4-triazoles yields the mixtures of the salts of 1,4-dialkyl-, 1,4,5-trialkyl-3-nitro-1,2,4- triazoliums and 1,4-dialkyl-, 1,3,4-trialkyl-1,2,4-triazol-5-ones with predominance of quaternary salts.

Reactions of 1,3-dichloro-5-R-1,2,4-triazoles with methyl iodide yield mono- and bicyclic 1,4-dimethylthiazolium salts.In addition, 3-chloro-5-R-1,2,4-triazoles unsubstituted at the nitrogen atoms and N-monomethyl derivatives are formed.

The reaction of methyl iodide with N-chloro-3-nitro-, and N-chloro-5-methyl-3-nitro-1,2,4-triazoles leads to the release of iodine and the formation of a mixture of compounds containing 3-nitro-1,2,4-triazoles unsubstituted at the nitrogen, the N-mono- and N,N-dimethylated derivatives (triazolium salts), and the products from their further transformations (1,4-dimethyl-5-triazolones).
