| Abstract: | New unsymmetrical chiral Co(II) salen complexes were synthesized and the efficiency of these catalysts was examined in the enantioselective reduction of aromatic ketones. The higher level of enantioselectivity was attainable over chiral Co(II) salen complexes prepared from salicylaldehyde and 2-formyl-4,6-di-tert-butylphenol derivatives. |
