A facile method for the trifluoromethylsulfinylation of activatedarenes with trifluoromethanesulfinyl chloride in the presence of Lewis acid was developed. The protocol could be expanded to the perfluoroalkylsulfinylation of activatedarenes, as well as the trifluoromethylsulfinylation of indoles without additive.

The monoreduction of trifluoromethanesulfonyl chloride by an appropriate phosphine, preferentially tricyclohexylphosphine, generates the reactive trifluoromethanesulfinyl chloride CF3SOCl as donor of CF3S(O)+ cation. The direct trifluoromethylsulfinylation of indoles, pyrroles, other azaarenes, amines, and phenols was successfully achieved in moderate to high yields.
