Abstract: Xylylenebis(3-benzothiazolium bromides) and 3-(bromomethylbenzyl)benzothiazolium bromides were prepared by the reaction of benzothiazole, 6-methyl-, 6-methoxy-, 6-bromo-, 2-methyl-, 4-methyl-, and 2-styrylbenzothiazole with 1,2-, 1,3-, and l,4-bis(bromomethyl)benzene. The formation of not typical tricyclic compounds has been proved by the reaction of 3-methyl-2-benzothiazolinethione with 1,2- and l,3-bis(bromomethyl)benzene. Using l,4-bis(bromomethyl)benzene, 2-methylthio-3-methylbenzothiazolium bromide is formed. The mechanisms of these reactions are proposed. The structure has been proved by the ¹H NMR spectra.
