Photocatalytic Aerobic Oxidation by a Bis-porphyrin-Ruthenium(IV) μ-Oxo Dimer: Observation of a Putative Porphyrin-Ruthenium(V)-Oxo Intermediate

The title complexes catalyze the aerobic oxidations of hydrocarbons using visible light and atmospheric oxygen as oxygen source in sequences employing photodisproportionation reactions. The putative oxidants, ruthenium(V)-oxo porphyrin species, can be detected and studied in real time via laser flash photolysis methods.
