We developed a distal C–H functionalization of electron-rich arenes such as alkoxyarenes using diverse coupling partners through organic photoredox catalysis. Our reaction features radical–radical coupling between cyclohexadienyl radical and various persistent radical. A range of functional groups, including sp² carbon-based groups such as alkoxycarbonyl and pyridyl, as well as heteroatom-containing groups like sulfonyl, and alkyl groups were successfully introduced.
