Abstract
Chlorination of 4-fluoro-5-(1,1,2,2-tetrafluoroethyl)-1,2-dithiole-3-thione with an equimolar amount of chlorine or sulfuryl chloride gives 3-chlorosulfanyl-4-fluoro-5-(1,1,2,2-tetrafluoroethyl)-1,2-dithiolium chloride. The reaction of the title compound with excess chlorinating agent leads to 3,3,4,5-tetrachloro-4-fluoro-5-(1,1,2,2-tetrafluoroethyl)-1,2-dithiolane. By oxidation and oxidative imination of 4-fluoro-5-(1,1,2,2-tetrafluoroethyl)-1,2-dithiole-3-thione, the corresponding S-oxide and sulfimide were obtained, respectively.
