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.
