Outline of Final Research Achievements

Model complexes of oxy-PHM were prepared and examined in dioxygen reactivity. The formed mononuclear Cu(II)-end-on-superoxide complexes exhibited C-H bond hydroxylation at the benzylic position of a ligand phenetyl side arm at higher temperature.
As model complexes of molybdoenzymes, molybdenum complexes having a terminal oxide, sulfide, and selenide group were prepared and the crystal structure, electronic structures, and reactivities were examined in a systematic way.
Model complexes of iron enzymes were synthesized and the reactivities were examined in the oxidation reactions. The complexes were found to catalyze alkene dihydroxylation with hydrogen peroxide as a terminal oxidant. In the presence of amines, the alkenes were converted to aminoalcohols. When 1,5-dienes were employed as the substrate, the oxidative cyclization proceeded to yield the corresponding tetrahydrofurans.
