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.

The present invention relates to conjugated polymers which contain specific fused arylamine structural units. The inventive materials have improved efficiency at a high illumination density and are therefore suitable in particular for use in what are known as passive matrix displays.

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.
