Tin-free radical cyclization reactions initiated by visible light photoredox catalysis.
Herein, we report an advancement in the application of visible light photoredox catalysts in a classic free radical mediated 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 visible light induced catalytic cycle.
