A selective and facile trifluoromethylation process for a wide range of thiophenols and thiols under metal free conditions has been developed using two simple and safe solids, sodium trifluoro-methanesulfinate and iodine pentoxide, via the radical process.
Mild electrophilic trifluoromethylation of carbon- and sulfur-centered nucleophiles by a hypervalent iodine(III)-CF3 reagent
Kieltsch, Iris,Eisenberger, Patrick,Togni, Antonio
, p. 754 - 757 (2007/10/03)
Inexpensive, recyclable, and activable: these are the features of a new mild electrophilic trifluoromethylation reagent that can be used to transfer a CF3 group to C-centered nucleophiles, such as β-keto esters and α-nitro esters, and to S-centered nucleophiles (see scheme).

Ion-radical perfluoroalkylation. Part 11. Perfluoroalkylation of thiols by perfluoroalkyl iodides in the absence of initiators

Perfluoroalkylation of aliphatic, aromatic and heterocyclic thiols by perfluoroalkyl iodides in the presence of Et3N appears to occur spontaneously under daylight or the usual laboratory lighting conditions at 20-22 deg 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 (2percent-3percent) and depends directly on the temperature, lighting, solvent polarity and electronic properties of the perfluoroalkylating agents and of the thiol substituents.At the same time, formation of diaryl disulphides frequently occurs contrary to above rules.The reaction mechanism is discussed. - Keywords: Ion-radical perfluoroalkylation; Thiols; Perfluoroalkyl iodides; Reaction mechanism; Nucleophilicity; NMR spectroscopy
