Asymmetric epoxidation using a singly-bound supported Katsuki-type (salen)Mn complex.
We have successfully prepared an unsymmetrical analogue of a Katsuki-type salen ligand having a single hydroxyalkyl group at its 6-position, and also its Mn(III) complex; attachment of the complex to a polymer gives a highly enantioselective and recoverable catalyst for epoxidation of 1,2-dihydronaphthalene.
