Aromatization of Enamines Promoted by a Catalytic Amount of Pd/C. Synthesis of Aromatic Amines
摘要:
[GRAPHICS]Aromatic amines were obtained efficiently from enamines by using a catalytic amount of Pd/C in the presence of nitrobenzene and 4 Angstrom molecular sieves in refluxing toluene.

Enamines were tested to be efficient nucleophiles for palladium-catalyzedasymmetric allylic alkylation, avoiding the use of unstablilized ketoneenolates formed by strong bases. The influence of the chiral metallocene-based ligands upon this reaction was studied in detail. It was shown that planar chirality played an important role in enantioselectivities. Meanwhile, different kinds of enamines and
