The combination of Mo(CO)(6) and 10 Mol % of palladium acetate catalyzes the transformation of 2-nitroarenes to 3H-indoles through a tandem cyclization-[1,2] shift reaction of in situ generated nitrosoarenes. Mo(CO)(6) appears to have dual roles in this transformation generate generate CO and promote C-N bond formation to increase the yield of the N-heterocycle product.

Rh-2(II)-Complexes trigger the formation of 3H-indoles from ortho-alkenyl substituted aryl azides. This reaction occurs through a 4 pi-electron-5-atom electrocyclization of the rhodium N-aryl nitrene followed by a [1,2]-migration to afford only 3H-indoles. The selectivity of the migration is dependent on the identity of the beta-styryl substituent.
