Herein, we report an advancement in the application of visiblelight photoredox catalysts in a classic free radicalmediated reaction, cyclization onto unactivated pi-systems. The reactive radical intermediate is generated by the single electron reduction of an activated C-Br bond by an electron-rich redox catalyst afforded by a visiblelight induced catalytic cycle.
