temperature. The reaction proceeds selectively and does not require the presence of any additive. A mechanism is proposed based on the obtained results of EPR as well as luminescence The visible-light-mediatedsynthesis of trifluoromethylthiolated arenes in the presence of ruthenium-based photocatayst under mild reaction conditions is reported. The trifluoromethylthiolated arenes are obtained using the shelf-stable

This invention relates to a process for preparing perfluoroalkyl aryl sulfides by reaction of disulfides with alkali metal salts of aliphatic perfluorocarboxylic acids in the presence of a high-boiling aprotic solvent at elevated temperature and reduced pressure, wherein the product formed is distilled off at the rate at which it is formed. This invention further relates to the novel compounds 2-nitrophenyl pentafluoroethyl sulfide and 2-aminophenyl pentafluoroethyl sulfide.

efficiently converted into the corresponding trifluoromethylthio‐ or selenoethers by reaction with Me4NSCF3 or Me4NSeCF3, respectively, in the presence of catalytic amounts of copper thiocyanate. These Sandmeyer‐type reactions proceed within one hour at room temperature, are applicable to a wide range of functionalized molecules, and can optionally be combined with the diazotizations into one‐pot protocols

It's so easy! Direct trifluoromethanesulfanylation reactions remain difficult to perform because of the lack of reagents that are stable and easy to handle. Trifluoromethanesulfanamides are reagents which, in combination with readily available Grignard reagents, can be used by those without experience in fluorine chemistry to easily synthesize trifluoromethylthioethers.

sodium thiocyanate and the inexpensive, easy-to-use trifluoromethylating reagent Me3Si–CF3, diazoniumsalts are smoothly converted into the corresponding aryl trifluoromethyl thioethers. Combined with diazotisation, this convenient and inexpensive method allows the straightforward synthesis of aryl or heteroaryl trifluoromethyl thioethers from the corresponding anilines.
