J Org Chem. 2019 Sep 6;84(17):11210-11218. doi: 10.1021/acs.joc.9b01400. Epub 2019 Jul 30.

Abstract

Copper-catalyzed aerobic oxidative C-S bond 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.
