Sakovich, G. V. published the artcileAlkylation of 4(5)-nitro-1,2,3-triazole with alcohols in strongly acidic media, HPLC of Formula: 84406-63-3, the publication is Russian Chemical Bulletin (2013), 62(1), 111-116, database is CAplus.
Alkylation of 4(5)-nitro-1,2,3-triazole with alcs. in concentrated H2SO4 occurs at all three endocyclic N atoms, giving a mixture of isomeric N(1)-, N(2)-, and N(3)-alkyl-4-nitro-1,2,3-triazoles (alkyl is iso-Pr, sec-Bu, and cyclohexyl). The selectivity of the alkylation depends on the alc. used. The most selective alkylation is provided at the N(2) atom when iso-Pr (81%) and sec-Bu alcs. are used (67%). With an increase in the reaction time, also in the order isopropyl-, sec-butyl-, and cyclohexyl-4-nitro-1,2,3-triazoles, the N(2)-isomers undergo isomerization into N(1)-alkyl-4-nitro-1,2,3-triazoles. In all the cases, the fraction of the N(3)-substitution products in the mixtures is 6-30%.
