Immobilization of Bis(Bipyridine) BINOL Ligands and Their Use in Chiral Resolution
摘要:
An enantiomerically pure bis(bipyridine) BINOL ligand was synthesized which was functionalized with an iodine substituent in its periphery. Using this halogen function, the ligand was immobilized on a commercially available polystyrene gel via Suzuki cross-coupling. The functionalized gel was found to be effective in the chiral resolution of similar bis(bipyridine) ligands based on a Troger's base core.
