We have developed a highlyselectiveone-pot method for the synthesis of (E)-vinyl sulfones and sulfoxides from thiols with terminal alkynes. The sulfones and sulfoxides could be obtained with excellent selectivity in good isolated yields. It is simple, efficient and environmentally benign, and metal-free. The mechanism for the formation of the (E)-vinyl sulfones was also proposed.

(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

Copper-catalyzed hydrosulfonylations of alkynes can be carried out using sodium sulfinates in air. The procedure affords syn-selectively (E)-alkenyl sulfones in good yields. Then, both terminal and internal alkynes are available.

β-(Phenylseleno)vinylsulfones are readily available from the selenosulfonation of acetylenes and undergo efficient, stereoselective substitution of the phenylseleno moiety by the alkyl group of alkyl (phenylseleno) cuprates.
