practical and mild synthetic protocol for a three-component reaction among alkenes, trifluoromethyl aromatics, and arylthiols. In this reaction, the selective C–F activation of trifluoromethyl aromatics occurs. The arenethiolate in the system plays dual roles: an electron donor and a radical trapping reagent. This process only releases a fluoride anion as a by-product within 2 hours. Moreover, the obtained

Although defluorinative functionalization of trifluoromethylarenes has been studied by several research groups, different kinds of catalysts are required accordingly based on specific substrate families to obtain the corresponding RCF2Ar compounds. Herein, we report a general photocatalytic approach for the selective hydrodefluorination (HDF) and defluoroalkylation (DFA) of ArCF3. Using electronically-different
