Immobilization of dicationic Mn(III) salen in the interlayers of montmorillonite clay for enantioselective epoxidation of nonfunctionalized alkenes
Dicationic chiral Mn(III) salen complex (0.4 mol%) immobilized in the interlayer of montmorillonite clay 4A, epoxidize bulkier alkenes ( epoxide yield 68 - 99%) with high chiral induction ( up to 95% ee) with a catalyst reusability of up to four cycles.
