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.

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.
