Exogenous Photocatalyst-Free Aryl Radical Generation from Diaryliodonium Salts and use in Metal-Catalyzed C–H Arylation

By Jonathan Galicia and others at

We demonstrate 1) that halogen bonding is not critical for enabling light-driven radical generation from diaryliodonium salts and 2) radi-cals generated by this route can be captured by transition-metals for C–H arylation reactions. These results are the first step toward devel-oping new metal-catalyzed aryl radical couplings without exogenous photocatalysts.
