Photocatalytic Oxidation of Organic Compounds in Water by Using Ruthenium(II)–Pyridylamine Complexes as Catalysts with High Efficiency and Selectivity

Abstract

The photocatalytic oxidation of organic substrates such as alcohols was conducted in the presence of RuII–aqua complexes as oxidation catalysts, [RuII(bpy)3]2+ as a photosensitizer and electron mediator, and a CoIII complex as a sacrificial oxidant (see scheme). The catalytic systems exhibited high efficiency to achieve turnover numbers of over 8000.
