Direct trifluoromethylthiolation of terminal alkynes mediated by a hypervalent trifluoromethylthio-iodine(iii) reagent; boosting effect of fluorinated alcohol

We reported a direct simple trifluoromethylthiolation reaction of various terminal alkynes using a new hypervalent trifluoromethylthio-iodine( iii ) reagent TFTI in a fluorinated alcohol, either hexafluoro-2-propanol or perfluoro- tert -butanol.
