Chlorolysis of beta-functionalized alkyl polyfluoroalkenyl sulfides giving rise to beta-functionalized polyfluoroalkenesulfenyl chlorides was examined. beta-Cyano-containing sulfenyl chlorides underwent intramolecular cyclization at the nitrile group to form substituted isothiazoles.
A new method was developed for the synthesis of fluorine-containing functionally substituted vinyl sulfides and ketene dithioacetals from the corresponding derivatives of a-trifluoromethyl-substituted CH-acids and thiols in the presence of BF(3) . NEt(3).
