Abstract

The product of substitution at the nitrogen atom N(4) is found along with main N(1)- and N(2)-substituted 5-R-3-nitro-1,2,4-triazoles among the products of 5-R-nitro-1,2,4-triazolate anion (R = H, Me, Et) reactions with diethyl sulfate in aqueous medium. The fraction of 5-R-4-ethyl-3-nitro-1,2,4-triazoles, which varies from 1.3 to 6.9%, depends on the temperature, ratio of the starting reagents, and the degree of the alkylating agent consumption.
