In this study, a catalyst-free visible-light-driven C(sp(2))-H arylation of unprotected phenols with arylbromides was developed to obtain 2-arylated phenols. This reaction occurs through the excitation of an electron donor-acceptor complex between a phenolate and an arylbromide, electron transfer, and debrominative C(sp(2))-C(sp(2)) coupling.
