The use of copper-catalyzed visible light photochemistry and the Zhdankin azidoiodinane reagent enables an azidation method for C-N bond formation at benzylic C-H positions via a radical chain reaction. The method is applicable to a wide range of substrates bearing different functional groups and having a primary, secondary, or tertiary benzylic position.
