We report that bromination of aliphatic and benzylic sp3 C[BOND]H bonds can be achieved with visible light photoredox catalysis by using a low loading of Eosin Y disodium salt, an inexpensive organic dye, as a photoredox catalyst. The light source is a low-power household lamp and the reaction can b...
