Synthesis of Chiral Cobalt Complexes with Planoid-Tetradentate Ligand System

Article abstract of DOI:10.1002/hlca.19930760120

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.
