A high‐valent trans ‐dioxorhenium( V ) complex containing pyridine ligands was successfully immobilized on an ITO (indium‐doped tin‐oxide) electrode. The complex formed a monolayer structure on the electrode surface and promoted electrochemical catalytic oxidation of 1‐phenylethanol to acetophenone in CH 2 Cl 2 . Oxidation hardly occurred in CH 2 Cl 2 solution containing the free rhenium( V ) complex. Immobilization of other high‐valent metal complexes will present opportunities for design of functional electrodes with high activities. (© Wiley‐VCH Verlag GmbH & Co.
