Abstract

Perhalogenated ruthenium porphyrins were found to be efficient catalysts for the oxygenation of hydrocarbons including secondary alkanes and benzene in the presence of 2,6-dichloropyridine N-oxide under mild conditions in aprotic media. Up to 15,000 turnovers and rates of 800 TO/min were obtained. A mechanism where Ru(III) - Ru(V) intermediates play an important role is proposed and discussed. The search for new methods for the catalytic oxygenation of hydrocarbons is one of the most important directions of modern chemistry [1]. Among the metalloporphyrin-mediated oxidations, ruthenium catalysts display remarkable activity for aerobic oxidations [2] (Fig. 1) and promising reactivity with N2O [3].
