An easily accessible, anion-functionalized ionic liquid, 1-ethyl-3-methylimidazolium (S)-2-amino-3-methylbutyric acid salt, [emim][Val], has been demonstrated to be an efficient additive for the CuI-catalyzed coupling reaction of sulfinic acid salts with aryl iodides, aryl bromides and vinyl bromides, leading to the formation of sulfones in good yields.

Synthetically and pharmaceutically useful vinyl sulfones and sulfonamides are synthesized by the direct coupling of thiosulfonates with alkenes and amines, respectively. Copper catalysts help to generate the sulfonyl group from thiosulfonates and to form the C(sp2)–S/N–S bonds of the organosulfur compounds. This paper discusses the scope of these reactions of aromatic and aliphatic thiosulfonates with alkenes and amines.

A practical metal-free procedure for the synthesis of (E)-vinyl sulfones has been developed through the coupling of β-nitrostyrenes with sodium sulfinates under microwave irradiation. This methodology provides a convenient and efficient approach to various (E)-vinyl sulfones from readily available starting materials with excellent regioselectivity. The present oxidative reaction involves an efficient denitrative radical cross-coupling of β-nitrostyrenes with sodium sulfinates via using AcOH as an additive.
Visible-Light-Enabled Decarboxylative Sulfonylation of Cinnamic Acids with Sulfonylhydrazides under Transition-Metal-Free Conditions

, p. 2990 - 2993 (2016)
Decarboxylative cross-coupling reactions of cinnamic acids with sulfonylhydrazides were explored using oxygen as the sole terminal oxidant, realizing a conceptually novel technology for vinyl sulfone synthesis under the synergistic interactions of visible light irradiation, organic dye-type photocatalyst eosin Y, KI, and Cs2CO3 at room temperature.

, (2022/04/09)
Selective sulfonylation and oxosulfonylation of alkenes with sulfinates have been developed via anodic oxidation in an undivided cell. The novel electrosynthetic method provided β-keto sulfones and vinyl sulfones with good to excellent yields in the absence of any transition metal catalyst and oxidants. Mechanism studies show that two different pathways involved in these two transformations.

Herein, we describe a practical protocol for efficient, mild, visible-light-induced three-component intermolecular trifluoromethyl-alkenylation reactions of unactivated alkenes. The protocol has good functional group tolerance and a broad substrate scope. Using this protocol, we not only introduced a trifluoromethyl group into alkenes but also converted unactivated alkenes to styrene-based activated alkenes, in addition to accomplishing late-stage functionalization of pharmaceutical intermediates. (Figure presented.).
Base-controlled divergent synthesis of vinyl sulfones from (benzylsulfonyl)benzenes and paraformaldehyde
Xiao, Fuhong,Hu, Yangling,Huang, Huawen,Xu, Fen,Deng, Guo-Jun
, p. 3527 - 3535 (2020/05/25)
A tuneable metal-free protocol for the selective preparation of a-substituted vinyl sulfone and (E)-vinyl sulfone derivatives has been described. In this process, stable paraformaldehyde was used as the carbon source. The base played an important role in the selectivity control of transformations. More than 50 products were synthesized with excellent chemoselectivity and broad functional group tolerance.
