Abstract

A versatile photoredox-catalyzed three-component sulfonylation of diaryliodonium salts with DABSO and silyl enolates involving the insertion of SO₂ was developed. Moreover, by employing β-alkyl substituted silyl enolates as substrates, the sulfonylation would give α-alkyl substituted β-keto sulfones, which are difficult to accessed by previous method involving the insertion of SO₂.
