Abstract
New polymer supported Co(III)-salen-X (X = acetate, camphorsulfonate, BF4) catalysts with different counter-ions are synthesized and evaluated in the hydrolytic kinetic resolution of epichlorohydrin. The polymer resin supported catalysts are effectively recovered after reaction by filtration and reused in subsequent reactions with similar selectivity. The recycled catalysts give decreased reaction rates, and the deactivation is dependent on the counter-ion.
