| Research Abstract |
Stereoselective oxidation is an important chemical process in academy and / or industry and iron complexes with high efficiency and high stereoselectivity are required for environmentally friendly process. Since a dinuclear core structure of iron(III) complex developed by us is a key core structure of nonheme dinuclear iron enzyme such as alkane monooxygenase, it has been studied enhancing the catalytic oxidation properties of the synthesized dinuclear iron(III) complexes by means of introduction of chiral substitute and I or sterically hindered substitutes in the ligands. Several N2O2 chiral tetradentate ligand including amide binding sites external to the ethylenediamine and their dinuclear iron(III) complexes have been synthesized. The catalytic properties for sulfoxidation with hydrogen peroxidewere examined. The iron(III) complex with chiral ligand including tertiary amides is most active compared to the complexes including secondary amide nor achiral ligands. To study the structural detail of these complexes, mononuclear metal complexes with these chiral ligands have been examined and it was clear that the structure of metal complex with chiral ligand including secondary amine is opposite to that if metal complex with chiral ligand including tertiary amides. The helicity of the complex is also influenced by counter anions.
