A wide range of N-arylated indoles are selectively synthesized through intermolecular C(aryl)–N bond formation from the corresponding aryl iodides and indoles through Ullmann-type coupling reactions in the presence of a catalytic amount of easily available N,N,N′,N′-tetramethyl-BINAM–CuI complex under very mild reaction conditions.

The N-arylation of indoles, including a variety of substituted ones, has been carried out using bulky, electron rich phosphines as the supporting ligand in combination with Pd-2(dba)(3). Using this catalyst system, the efficient coupling of indole and a variety of substituted indoles with aryl iodides, bromides, chlorides, and triflates can be achieved.
