The chiral salen Mn(III) complexes were heterogenized on the siliceous MCM-41 by a new grafting method using (3-aminopropyl) trimethoxysilane and 2,6-diformyl-4-tert-butylphenol. The immobilized chiral salen Mn(III) complexes were stable during the reaction and exhibited a relatively high enantiosel
