Abstract
Herein, we developed a novel visible-light-induced photoredox platform for general three-component difunctionalization of alkenes with aqueous sulfoxonium ylides as carbon radical precursors. This reaction utilizes various alkenes as substrates and employs cost-effective, non-toxic metal salts as halogen donors. The process proceeds under mild aqueous conditions without requiring acid or base additives, offering a simple and environmentally benign strategy for the synthesis of structurally diverse C(sp3)-rich organic halides with excellent chemo- and regioselectivity profiles.
