Visible Light‐Driven Eosin Y‐Catalyzed Suzuki‐Type Sulfonylation

A strategy for sulfonylation of boronic acids with sulfonyl chlorides has been established via Suzuki-type radical cross-coupling. This approach allows for the synthesis of more than 50 sulfone examples enabled by photoredox catalysis under visible light radiation. Moreover, the title reaction is applied in late-stage functionalization of bioactive molecules, and further transformation of the resulting sulfones into 2-functionalized sulfones, borates, triphenylphosphine oxide and N-arylcarbazole can be also achieved.
