Rhodium‐Catalyzed Direct Amination of Arene C‐H Bonds Using Azides as the Nitrogen Source

Abstract The article reports the practical procedure of the direct C ‐ H amination and amidation reaction of arenes using aryl sulfonyl azides as the source of the nitrogen functionality, which releases molecular nitrogen as the single by‐product. This reaction is catalyzed under mild conditions by a cationic rhodium complex [Cp*Rh(III)]2+( SbF 6 )2 2‐ (Cp*, ?5‐pentamethylcyclopentadienyl) without requiring external oxidants. This procedure offers a very efficient and practical route to aryl amines and amides.
