motifs in the pharmaceutical chemistry, is highly atom- and step-economical. However, the singleC(sp3)-F bond cleavage of ArCF3 is a great challenge because of the chemical inertness of the C(sp3)-F bond and the difficult selectivity control of monodefluorination. We report here the first example of singleC(sp3)-F functionalization of trifluoromethylarenes via visible-light catalysis merged with
