抄録

Dioxygen binding and activation by non-heme type transition metal complexes are of current interest due to its importance in biological system and industrial processes. Since active-oxygen species generated in catalytic cycles are reactive and unstable, it is difficult to identify those active-oxygen species and elucidate reaction mechanisms. To overcome such difficulties, it is essential to synthesize model complexes which can stabilize active-oxygen species by constructing proper coordination environments around metal centers using the stereoelectronic effect of the supporting ligand. Those models allow us to observe a variety of active-oxygen species and to elucidate their reactivity and oxidation reaction mechanisms. In this account, we report syntheses of non-heme type transition metal complexes having a variety of observable active-oxygen species, which are capable of performing the following functionalities: 1) reversible dioxygen binding by diiron(II), cobalt(II), and copper(I) complexes, 2) reversible breaking and making the O-O bond by dicopper and mononuclear iron complexes, 3) a variety of oxidation reactions mediated by high-valent bis(μ-oxo)dicopper(III) and dinickel(III) complexes, cis-(μ-1,2-peroxo)diiron(III) and (μ-η22-peroxo)Cu(II)2 complexes as functional models for the dioxygen activating dimetalloenzymes such as methane monooxygenase, toluene monooxygenase, etc.
