Reactions of 3-nitro-1,2,4-triazole derivatives with alkylating agents. 8*. Alkylation of 3-nitro-5-R-1,2,4-triazoles with derivatives of diethylene glycol in the presence of alkali
摘要:
The interaction of 3-nitro-1,2,4-triazole and 5-methyl-3-nitro-1,2,4-triazole with bifunctional agents - beta, beta'-dichloro- and beta, beta'-(dinitroxy) diethyl ethers - in the presence of alkali proceeds with the formation of a mixture of products substituted at the N(1) and N(2) atoms of the heterocycle, consisting of three reaction products, the N(1), N'(1)-, N(1), N'(2)-, and N(2), N'(2) isomeric derivatives of nitrotriazoles. Replacement of the Cl leaving group in the alkylating agent by a NO2 group does not lead to a substantial change in the degree of conversion and overall yield of alkylation products. The ratio of N(1), N'(1):N(1), N'(2):N(2), N'(2) isomeric reaction products from 3-nitro-1,2,4-triazole was (82.0-85.7):(7.7-9.9):(6.6-8.1), and from 5-methyl-3-nitro-1,2,4-triazole was (76.9-79.8):(10.1:11.4):(10.1-11.7) respectively.
