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.

The construction of functionalized cyclopropanes is a hot topic in synthetic chemistry as they are important 3C starting materials and privileged structures in medicinal chemistry. By treating the readily available cyclopropenes with sulfonyl iodides in water, β-iodo cyclopropyl sulfones were diastereoselectively formed via a syn-addition process in high yields. Employment of water as the sole solvent
