Highly active new chiral Co(iii) salen catalysts immobilized by electrostatic interaction with sulfonic acid linkages on ordered mesoporous SBA-16 silica

Abstract

New chiral cobalt(III) salen complexes immobilized via HO3S-linkers on ordered SBA-16 by electrostatic interactions showed very high activity in enantioselective ring-opening reactions of racemic epoxides.
