Copper-catalyzed aerobic oxidative C–Sbond coupling reaction between thiophenols and aryl-substituted alkenes for (E)-vinyl sulfones synthesis is reported here. With air utilized as a green oxidant, this transformation not only produces various vinyl sulfones in moderate to good yields but also possesses a simple and ecofriendly system. To clarify the mechanism, kinetic experiments has been investigated
