A practical synthesis of perfluoroalkyl sulfides is described. The method employs stable and readily accessible thiosulfonates as new electrophiles with commercial nucleophilic perfluoroalkylating reagents. The mild reaction conditions allow access to a wide variety of both aryl- and alkyl-substituted perfluoroalkyl sulfides amenable to pharmaceutical development. Furthermore, the reaction operation

Perfluoroalkylation of aliphatic, aromatic and heterocyclic thiols by perfluoroalkyliodides in the presence of Et3N appears to occur spontaneously under daylight or the usual laboratory lighting conditions at 20–22 °C and is complete in 10–15 min to 2–3 h. An exception to this rule are thiols with a low nucleophilicity. The reaction is accompanied by thiol oxidation (2%–3%) and depends directly on

A copper-mediated oxidative pentafluoroethylthiolation of arylboronicacids with TMSC2F5 and S8 was developed. This reaction provides a new access to various aryl pentafluoroethyl thioethers. The use of 2-fluoropyridine as the ligand and the ability to carry out the reaction at 70 °C are key features of this oxidative coupling reaction.
