We report a palladium-free Wacker-type oxidation of styrenes using CuCl2/KBr as the catalyst and trichloroisocyanuric acid as a stoichiometric chlorine radical source. The reaction protocol is compatible with diverse functional groups, affording selectively acetophenones. The mechanistic analysis revealed that a site-selective sequential CuII-photooxidation/CuI-photoreduction of the intermediary chlorohydrin is the key to the success of this transformation. Copper acts as a site-selective photooxidant and photoreductant, thus enabling the Wacker-type oxidation of styrenes to acetophenones.
