Abstract
Quaternary thiazolium salts with active methylthio groups and 2-thiazolyl and 2-pyridyl residues attached to the nitrogen atom of the thiazole ring were obtained. 2-Methyl-3-(2-pyridyl)-and 2-methyl-3-(2-thiazolyl)thiazolium salts were synthesized by replacement of the methylthio group by a methyl group. Monomethylidynecyanines and nullmethylidyne- and dimethylidynemerocyanines were obtained from salts with active methyl and methylthio groups.
