The mechanism of Ce(IV) wateroxidation catalyzed by [Ru(tpy)(bpm)(OH(2))](2+) (tpy = 2,2':6',2''-terpyridine; bpm = 2,2'-bipyrimidine) and related single-sitecatalysts 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 Ru(V)=O(3+) and three peroxidic intermediates that have been characterized
