In this report, we describe the visible light photolysis of aryl diazoacetates in the presence of some <i>N-</i>heterocycles that enables mild, metal-free N-H functionalization reactions of carbazole and azepine heterocycles (15 examples, up to 83% yield).The Journal of organic chemistryVisible Light Induced Metal-Free Carbene <i>N</i>-Carbazolation.PMC6900254716136Koenigs RMEmpel CPatureau FWfalseVisible Light Induced Metal-Free Carbene <i>N</i>-Carbazolation.Metal-free N-H functionalization reactions represent an important strategy for sustainable C-N coupling reactions.
