Abstract

An efficient method for visible-light-mediated sulfonylation/arylation of the C–C σ-bond in vinylcyclopropanes with sulfonyl chlorides to synthesize 1-sulfonylmethyl-substituted 3,4-dihydronaphalenes has been developed. A radical-type pathway has been proved in this transformation. This difunctionalization procedure shows a series of advantages, such as the use of commercially and easily available sulfonyl chlorides, mild conditions, and eco-friendly energy.
