Abstract: When studying the effect of the medium on methylation of 2-alkylthiobenzothiazoles with methyl iodide it was found that the alkyl group was eliminated and 2-methylthio-3-methylbenzothiazolium iodide was formed. From 3-alkyl-2-benzothiazolinethiones 2-methylthio-3-alkylbenzothiazolium iodide or 2-methylthio-3-methylbenzothiazolium iodide was formed in dependence on the chosen medium. The structures of the synthesized 2-alkylthio-3-alkylbenzothiazolium salts were proved by their ¹H NMR spectra. The synthesized compounds showed growth-regulating activities.
