Abstract

Abstract New chiral thiophene-salen ligands have been synthesized and the corresponding chromium complexes proved to beefficient catalysts for promoting asymmetric hetero-Diels– Alder reactions with good activities and high enantioselectivities (up to 88% ee). These complexes were successfully electropolymerized to give chiral polymers as insoluble powders for use in asymmetric heterogeneous catalysis. When engaged in successive ...
