Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The UV spectra of a number of 3(5)-nitro-1,2,4-triazoles at 220–350 nm were studied. A dependence of the position of the K band in the spectra of 3-nitro-5-R-triazoles on the nature of the substituent (R) is shown, and transfer of the effect of direct polar conjugation through the triazole ring was detected. Correlation dependences between the frequency and σ +n (σ +n -σ 0) constants were found in the series of 1-methyl-3-nitro-5-R-triazoles.
