We report herein a highly enantioselective synthesis of multisubstituted biaryl chlorides/iodides by sequential halogenation reactions (desymmetrization/kinetic resolution sequence). The selectivity of biaryl chlorides/iodides obtained in the first asymmetric reaction (desymmetrization) could be enh...
