Abstract

Abstract The chiral ligand 1, 1′-bi-2-naphthol (BINOL) has been succesfully immobilized on polystyrene. Several dendritic and non-dendritic BINOL derivatives (3, and 13–17), bearing at least two polymerizable styryl groups, were prepared and fully characterized. Suspension copolymerization of the MOM-or TIPS-protected cross-linking BINOL ligands (MOM= methyloxymethyl, TIPS= triisopropylsilyl) with styrene, cleavage of the protecting-groups, ...
