The cationic complex [(pymox-Me2)RuCl2]+BF4- is a highly effective catalyst for the C-H bond oxidation of aryl alkanes in water using tert-butyl hydroperoxide as oxidant to yield various aryl ketones at room temperature in water as solvent. A solvent-caged oxygen rebounding mechanism via a Ru(IV)-oxo intermediate species is suggested.
