The highly functionalized organofluorine compounds 3a-c were prepared from the activated dichlorinated sulfides 2a-c by displacement of a chlorine atom using nucleophilic fluorination agents such as dihydrogenfluoride polymer-supported. Fluorination of sulfoxides 5a-c with diethylaminosulfur trifluoride gives monofluoro sulfides 6a-c, subsequently transformed into α-chloro-α-fluoro sulfides 3a-c and sulfones 7a-c.
