| Abstract |
High-valent metal complexes have been extensively studied for its important role of the catalytic reaction in the inorganic chemistry field. In particular, the cobalt-oxo species has been found as a reactive intermediate in several reactions, such as water oxidation, sulfoxidation reaction, and C-H activation. In this regards, the investigation of high-valent cobalt-oxo species has been highlighted in the bioinorganic, organometallic and organic chemistry fields. For several decades, a series of studies have been conducted in an attempt to mimic the biological oxidation reaction. In spite of the huge efforts, few spectroscopical studies have been carried out to suggest cobalt-oxo complexes in the bioinorganic system because of the difficulty in preparing for short-lived metal-oxo species. Herein, the studies of high-valet cobalt-oxo compounds are reported with an N4 ligand. Multi-frequency and multi-technique EPR experiments to investigate [Co(O)L(Cl)] intermediate were performed to reveal the electronic and geometric information about the high-valent cobalt complexes. In particular, pulsed EPR techniques were performed to examine the oxo moiety with 17O labeled complex. |
