Visible-light-induced surfactant-promoted sulfonylation of alkenes and alkynes with sulfonyl chloride by the formation of an EDA-complex with NaI in water at room temperature
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 radicals generated from sulfonylhydrazides by the Bu4NIâtert-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.
