Ruthenium(II)-porphyrin (0.5 mol%) catalyzed N-imidations of aromatic nitrogen heterocycles with phenyl(tosylimino)iodinane under mild conditions were achieved in good yields (<94%). The effects of substituent, catalyst, temperature, and solvent on the reaction have been investigated. It was found that the catalyst significantly affected the yield and selectivity of imidation reaction for aromatic nitrogen heterocycles at 30 °C.
