Halogen-Carbon-Sulfur Compounds: Syntheses with 1,1,1,4,4,4-Hexafluoro-2-butene-2,3-bissulfenyl ChlorideThe bifunctional bissulfenyl chloride 3 is obtained by chlorination of the dithiete 1 or tetrathiocine 2. By excessive chlorination the saturated bissulfenyl chloride 4 is formed. 3 reacts with primary amines to yield the 1,3,2-dithiazoles 5a-e, whereas by reactions with active methylene compounds like ketones or β-dicarbonyls the compounds 7-14 are obtained with HCl elimination. 13 as well as 14 are converted into the carboxylic acid 15 from which the 1,3-dithiole 17 is obtained by decarboxylation. 3 reacts with disulfene to form tetrakis-(trifluoromethyl)tetrathiafulvalene as well as 4,4′,5,5′-tetrakis(trifluoromethyl)-2,2′-spirobi[1,3-dithiole] (18), whose crystal structure has been determined.
