A mild and efficient copper-catalyzed intramolecular carbotrifluoromethylation of alkynes has been achieved in the presence of Togni reagent as trifluoromethylating reagent. The reaction tolerates a range of substrates to give a group of trifluoromethylated heterocycles with high selectivities. A plausible mechanism was proposed on the basis of experimental results. And the Togni award goes to Copper-catalyzed intramolecular carbotrifluoromethylation of alkynes is carried out with a Togni reagent as the trifluoromethylating reagent (see scheme). Various trifluoromethylated heterocycles are synthesized in moderate to good yields. Moreover, a range of common functional groups is tolerated under the reaction conditions.
