I(III)-Mediated Arene C-H Amination using (Hetero)Aryl Nucleophiles

Herein, we report the metal-free oxidative C-H amination of arenes via a heterocyclic group transfer reaction from an I(III) N-HVI reagent. N-heterocycles serve as an oxidatively masked amine nucleophile and the resulting N-aryl pyridinium salts are inert to further oxidation. The products provide a versatile handle to access valuable aryl amine derivatives. The reaction proceeds under mild conditions and has good scope of both arene and N-heterocycle.
