The dual role of thiourea in the thiotrifluoromethylation of alkenes [PDF]

open access: yes, 2016
Alkenes substituted with a thiourea undergo C-CF3 followed by intramolecular C-S bond formation with the Togni reagent and trifluoroacetic acid (TFA) at room temperature; thiols and thioamides are not suitable S-sources for this reaction.
