Cross‐Coupling of Sodium Sulfinates with Aryl Heteroaryl and Vinyl Halides by Nickel/Photoredox Dual Catalysis

摘要

An efficient photoredoxickel catalyzed sulfonylation reaction of aryl, heteroaryl, and vinyl halides has been achieved for the first time. This newly developed sulfonylation protocol provides a versatile method for the synthesis of diverse aromatic sulfones at room temperature and shows excellent functional group tolerance. The electrophilic coupling partners are not limited to aryl, heteroaryl, and vinyl bromides and iodides, but also includes less reactive aryl chlorides as suitable substrates for this transformation.
