Abstract: Stability of 2-styryl-3-alkoxycarbonylmethylbenzothiazolium bromides, 2-styryl-3-benzylbenzothiazolium bromide, Perchlorate, tetrafluoroborate, nitrate, 2-styryl-3-allylbenzothiazolium bromide, and 2-styryl-3-propargylbenzothiazolium bromide in water was studied. At pH = 8 hydrolysis takes place and 2-styrylbenzothiazole, esters of  α-hydroxyacetic acid, benzyl alco­hol, allyl alcohol, and propargyl alcohol are formed. The rate constants of hydrolysis of the individual derivatives were determined.
