The directed difluoroacetamidation of unactivated arenes and heteroarenes with bromodifluoroacetamides via visible-light photoredox catalysis has been efficiently achieved at room temperature. Broad utility of this transformation is presented, including electronically deficient heteroaromatic and aromatic systems. The mechanistic pathway of the difluoroacetamidation was discussed based on photoluminescence quenching, spin-trapping, and kinetic isotope effect experiments.
