diaziridinone under palladium catalysis. A wide range of carbazoles were synthesized in good to excellent yields, and indolederivatives were obtained by using styrenes as the substrate. The palladacycles obtained from 2‐iodobiphenyls acted as the key intermediate, and the reaction should proceed via a tandem Pd‐catalyzedC−Hactivation/dual C−N bond formation sequence.

A novel A21-CuI catalyzed direct nitrogenation of biphenyl halides for the direct synthesis of carbazoles via a direct C–H amination process has been developed. A recyclable and inexpensive Cu-catalyst was successfully employed in N-heterocyclic compound synthesis via tandem azidation and C–H amination, which makes this protocol very practical and easy to handle.
