Abstract: Treatment of 2,3-dihydrothiazolo[2,3-b]benzothiazolium chloride and 2-methylthio-3-methylbenzothiazolium Perchlorate with N- and C-nucleophiles resulted in 3-methyl- and 3-(2-mercaptoethyl)-2-benzothiazolines. The reaction rate with C-nucleophiles was directly dependent on the concentration of triethylamine as catalyst. A new method for the preparation of 3-methyl-2-benzothiazolinone hydrazone and 3-methyl-2-(3-methylbenzothiazolinylidenamino)benzothiazolium Perchlorate is described. The results of tests for antimicrobial activity were not noticeable.
