coupling of enantiomerically enriched amines with aryl bromides produces the corresponding N-aryl derivatives. The choice of ligand in the palladium-catalyzed coupling is critical to the formation of the anilines without loss of enantiomeric purity. While LnPd (L = P(o-tolyl)3) successfully catalyzes the intramolecular aryl amination of α-subsituted optically pure amines, intermolecular coupling reactions
