Chemistry of Heterocyclic Compounds Aims and scope

Abstract

A method was developed for the preparation of 2-methyl-N-(2-thiazolyl)-, 2-methyl-N-(2-pyridyl)-, and 2-methyl-N-(2-benzothiazolyl)thiazolium salts. Cyanine dyes were synthesized from these salts. A comparison of the absorption spectra of dyes with various substituents (ethyl, phenyl, and 2-hetaryl) attached to the nitrogen atoms of the thiazole rings of the dyes demonstrated that the color deepens as the electronegativity of these substituents increases.
