Synthese chiraler Kobalt-Komplexe mit planoid-tetradentatem Ligand-System

Synthesis of Chiral Cobalt Complexes with Planoid-Tetradentate Ligand System The synthesis of a series of Cbl-related, achiral Co^III complexes 9a – c as well as enantiomerically pure, C²-symmetric Co^III complexes 15 and 18 , is reported (Schemes 3, 5, and 7). The crystal structures of 9c and 15 were determined. Complex 18 acts as an enantioselective catalyst in the isomerization of 1,4-epiperoxides to hydroxycycloalkenones.
