title: Modular approach for synthesis of vicinal diamines containing axial chiral 1,1'-binaphthyl from 1,2-diaminoethane by Pd-catalyzed N-arylation reactions.
abstract: A very convenient and efficient modular approach for the synthesis of vicinal diamines containing axial chiral 1,1'-binaphthyl from 1,2-diaminoethane by Pd-catalyzed N-arylation reactions has been developed. The resulting chiral diamines could be easily converted into NHC precursors, imidazole salts, in good yields.
