Visible‐Light‐Induced Metal‐Free Trifluoromethylselenolation of Electron‐Rich Heteroarenes Using the Nucleophilic [Me 4 N][SeCF 3 ] Reagent

A metal‐free visible‐light‐promoted regioselective trifluoromethylselenolation of electron‐rich heteroarenes has been developed using C–H functionalization. This eco‐friendly, atom‐economical, and easy‐to‐operate protocol provides direct access to a wide range of functionalized SeCF 3 ‐containing heteroarenes in high yields, and is amenable to continuous flow techniques. A radical mechanism was supported by EPR experiments.
