A green and efficient visible-light-induced iodosulfonyl reaction of alkenes in water using an EDA complex strategy at room temperature has been disclosed. The addition of a cationic surfactant allows for the easy formation of colored EDA complexes in water. The hydrophobic effect of the core in the surfactant aggregates, which act as a reaction medium formed by the surfactants themselves in water, plays a significant role in stabilizing the transition state and decreasing the activation energy of the reaction. Remarkably, transition-metal catalysts and organic solvents were not required in this transformation. Moreover, it displayed a broad substrate scope, good functional group tolerance, simple operation, scalability and high chemical selectivity. Thus, it not only provided a green and efficient synthetic strategy for the preparation of β-iodo-substituted sulfone derivatives, but also enriched the investigation of visible-light-induced reactions in water.

The regiospecific radical reactions of β-alkyl nitroalkenes with sulfonyl hydrazides depended to a great extent on the choice of a solvent and catalyst. In the presence of dimethylformamide (DMF), β-alkyl nitroalkenes more likely converted into electron-rich allyl nitro compounds, which reacted with sulfonyl hydrazides to afford allyl sulfones with high regioselectivity. While in acetonitrile (CH3CN), vinyl sulfones were obtained directly via sulfonation of electron-deficient β-alkyl nitroalkenes. The mechanism investigation revealed that the regioselectivity was controlled by the equilibrium of β-alkyl nitroalkenes and allyl nitro compounds.

A novel iodine-catalyzed functionalization of a variety of olefins and alkynes and direct decarboxylative functionalization of cinnamic and propiolic acids with TosMIC to provide access to various vinyl, allyl, and β-iodo vinylsulfones is described. This simple, efficient, and environmentally benign approach employing inexpensive molecular iodine as a catalyst demonstrates a versatile protocol for the synthesis of highly valuable sulfones, rendering it attractive to both synthetic and medicinal chemistry.

Sulfonyl chlorides were reduced to anhydrous sulfinate salts with magnesium under sonication. These sulfinates were alkylated to sulfones with alkyl chlorides in the presence of catalytic sodium iodide under sonication. A variety of aliphatic sulfones was efficiently prepared by this one-pot two-step procedure.

An oxidant-free dehydrogenative sulfonylation of α-methyl-styrene derivatives was developed for the construction of allylic sulfones by using eosin Y as a photosensitizer in conjunction with a cobaloxime catalyst. The process features a low-cost metal catalyst and atom economy, which provides an appealing strategy for future synthetic chemistry.

Sulfonyl radicals generated from sulfonylhydrazides by the Bu 4NI-tert-butyl hydroperoxide (TBHP) catalysis system underwent addition to a variety of α-methyl styrene derivatives to give the corresponding allylic sulfones. This selective allylic sulfonylation is metal-free, operationally simple, and environmentally friendly. The Royal Society of Chemistry 2012..
