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

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...

Description
Summary: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.
