Detection and Mechanistic Relevance of Transient Ligand Radicals Formed during [Ru(bpy)2(OH2)]2O4+-Catalyzed Water Oxidation.

The article reports that during the [Ru(bpy)2(OH2)]2O4+-catalyzed water oxidation, the detection and mechanistic relevance of transient ligand radicals has been formed. According to the author, the kinetic analyses of isotope evolution rates indicate that water exchange on {5,5} and intermediary oxidation states is very slow relative to O2 evolution.
