A stereoselective synthesis of (E)-vinyl sulfones has been developed via electrochemical oxidative N-S bond cleavage of aromatic sulfonylhydrazides, followed by cross-coupling reactions with cinnamic acids to form the C-S bond. The protocol proceeded smoo

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.
Aerobic copper-catalyzed synthesis of (E)-alkenyl sulfones and (E)-β-halo-alkenyl sulfones via addition of sodium sulfinates to alkynes

Copper-catalyzed sulfonylation of alkynes using sodium sulfinates in air produced regio- and stereoselectively (E)-alkenyl sulfones. When a CuCl catalyst was employed, the hydrosulfonylation proceeded syn-selectively, and (E)-alkenyl sulfones were synthesized in excellent yields. In contrast, the reaction using CuI catalyst produced (E)-β-haloalkenyl sulfones anti-selectively in the presence of potassium halides. Furthermore, the (E)-β-bromoalkenyl sulfones are possible to convert into various alkenyl sulfones by Suzuki-Miyaura coupling.
