Making introductions: The CF3S unit can be added in an electrophilic fashion to alkenes and alkynes in reactions with trifluoromethanesulfanylamide reagents (see scheme; Ts=toluene‐4‐sulfonyl). The products obtained may be of interest, for example, in pharmaceutical chemistry and materials science.
A redox-neutral, heavy-metal-free approach has been developed to realize deacylativethiolation of common ketones, which provides a unique method to introduce thioether groups site-specifically to unactivated aliphatic positions. Experimental and computational mechanistic studies suggest the involvement of a radical chain pathway.

[EN] The invention relates to a method for preparing new poly-fluorinated sulphanylamides and sulphinamidines and precursors thereof, and to the potential use of such sulphanylamides as potential substitutes for hydrophobic groups or carboxylic groups contained in some bioactive molecules, or as a perfluoroalkylsulphanylation agent. [FR] La présente invention concerne un procédé de préparation de nouvelles sulfanylamides et sulfinamidines polyfluorés ainsi que de leurs précurseurs et l'utilisation potentielle de ces sulfanylamides en tant que substituts possibles à des groupes hydrophobes ou à des acides carboxyliques contenus dans certaines molécules bio-actives ou encore en tant qu'agent de perfluoroalkylsulfanylation.
