Abstract

The mechanism of Ce(IV) water oxidation catalyzed by [Ru(tpy)(bpm)(OH 2)]2+ (tpy ) 2,2′:6′,2″-terpyridine; bpm ) 2,2′-bipyrimidine) and related single-site catalysts has been determined by a combination of mixing and stopped-flow experiments with spectrophotometric monitoring. The mechanism features O - O coupling by water attack on RuVdO3+ and three peroxidic intermediates that have been characterized by a combination of spectroscopy and DFT calculations.
