Abstract
The synthesis and the reactions of 5-arylimino-4-chloro-5H-1,2,3-dithiazoles, 4-chloro-1,2,3-dithiazole-5-thione, 4-chloro-1,2,3-dithiazol-5-one, 4-chloro-5,5-difluoro-5H-1,2,3-dithiazole, 5-alkylidene-5H-1,2,3-dithiazoles, 4,5-dialkyl-5H-1,2,3-dithiazoles, some 1,2,3-dithiazolium ions and 1,2,3-dithiazolyl radicals are critically discussed. Emphasis has been placed on the mechanistic interpretation of these reactions. Applications of 1,2,3-dithiazoles are also included.
