A copper(I)-catalyzed procedure for the synthesis of benzo[b]heterocycles. This protocol can be used to synthesize a variety of 2-arylbenzo[b]furans and indoles in good to excellent yields. This method can tolerate a variety of functional groups, does not require the use of expensive additives and is palladium-free.
