How Does Chiral Oxo(salen)manganese(V) Complex Discriminate the Enantioface of Simple Olefins? Scope and Limitation of Salen-Catalyzed Epoxidation

Abstract
Enantiofacial selection of simple olefins in salen-catalyzed asymmetric epoxidation was found to be controlled by two factors, repulsive steric interaction and π,π-repulsive electronic interaction.
