Formation and reactions of 1,4,2-dithiazolium cations
Abstract
3-Aryl-5-methylthio-1,4,2-dithiazolium salts, prepared by treatment of the corresponding 1,4,2-dithiazole-5-thiones with dimethyl sulphate, react with aniline and with active methylene compounds to form, respectively, 5-phenylimino- and 5-alkylidene-1,4,2-dithiazoles.
