(Bis(dimethylamino)carbazole) was used as photocatalyst in the reduction of unactivated aryl chlorides and alkyl chlorides in the presence of CHD as hydrogen atom donor at room temperature. The catalytic system can also be applied to the coupling of aryl chlorides with electron-rich arene and heteroarenes to affect C-C bond-forming reactions.
