Photocatalytic aerobic oxidation by a bis-porphyrin-ruthenium(IV) mu-oxo dimer: observation of a putative porphyrin-ruthenium(V)-oxo intermediate

Org Lett. 2010 May 21;12(10):2246-9. doi: 10.1021/ol1005938.

Abstract

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.
