Environment friendly protocol for enantioselective epoxidation of non-functionalized alkenes catalyzed by recyclable homochiral dimeric Mn(III) salen complexes with hydrogen peroxide and UHP adduct as oxidants

Environment friendly oxidants e.g. H2O2 and anhydrous urea hydrogen peroxide adduct (UHP) epoxidize non-functionalized alkenes (epoxide yield 40-99%) with high enantioselectivity (up to 94% ee) in 4-15 h using two recyclable homochiral dimeric Mn(III) salen complexes in presence of PyN-oxide with the catalysts reusability several times when UHP was used as an oxidant.
