One pot and selective intermolecular aryl- and heteroaryl-trifluoromethylation of alkenes by photoredox catalysis.
Résumé
We report herein the first photoredox-catalyzed intermolecular aryl- and heteroaryltrifluoromethylation of alkenes. Under the optimized conditions using Umemoto's reagent as a CF3 source, a wide range of styrenes can be readily difunctionalized, affording the corresponding trifluoromethylated adducts in up to 99% yield.
