By using [Ru(TTP)CO] [H2TTP = meso-tetrakis(4-tolyl)porphyrin] as catalyst and aryl azides as the nitrene source, the sp2(C–H) bonds of a series of indoles undergo oxidative C–N bond formation to give unique 2,3-diimination products in good to high yields.

CuI-2-(2′-pyridyl)benzimidazole catalyst system can serve efficiently to promoteN-arylation of various indoles to afford the N-arylated indoles. The bidentate ligand, 2-(2′-pyridyl)benzimidazole was proved superior to monodentate nitrogen-based ligands and well-known bidentate ligands such as 2,2′-bipyridyl and 1,10-phenanthroline.
