Palladium-Catalyzed Amination of Chloromethylnaphthalene and Chloromethylanthracene Derivatives with Various Amines
摘要:
Palladium-catalyzed amination of chloromethylnaphthalene and chloromethylanthracene derivatives to produce naphthylamines and anthrylamines in satisfactory to good yields has been developed. The unprecedented amination reactions proceeded smoothly under mild conditions in the presence of Pd(PPh3)(4) as a catalyst.
An unprecedented aromaticsubstitutionreaction of benzylic ammonium salts has been developed through palladium-catalyzed C-N bond cleavage. A range of primary and secondary amines participated in a palladium-catalyzed aromaticsubstitutionreaction of benzylic ammonium salts, delivering sterically hindered aromaticamines in moderate to excellent yields with extremely high regioselectivity.
