Immobilization of a High-Valent Rhenium Complex on an Indium-Doped Tin-Oxide Electrode: Enhanced Catalytic Activity of a trans-Dioxorhenium(V) Complex in Electrochemical Oxidation of Alcohols

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...

Zusammenfassung: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 CH2Cl2. Oxidation hardly occurred in CH2Cl2 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.
