Abstract

A three-component coupling of alkenes, sodium sulfinates and acyl imidazoles to access γ-keto sulfones with good functional group tolerance via cooperative N‒heterocyclic carbene (NHC)/photocatalysis is developed. Radical mechanism was proposed for the cascade reaction, revealing that a rare radical/radical cation cross-coupling reaction plays an important role.
