A transformation is presented that enables chemists to construct 4-aryl tetralones via visible-light-induced cyclodimerization-oxygenation of styrene under very mild conditions. Adding a catalytic amount of CuOAc obviously improves the yield. A mechanistic study reveals that the photoredox catalyst played the role of activating O2 while Cu affected the reactivity of reactive oxygen species (ROS).
