Solvent⁃dependent aryl sulfone synthesis under visible‑light conditions

A novel visible‑light‑driven solvent‑dependent strategy for the synthesis of aryl sulfones was demonstrated. With Ir（ppy）₃ as photocatalyst， aryl sulfonyl chlorides and boronic acids as substrates， potassium carbonate as base， 1，2‑dichloroethane as solvent and water as additive， the proposed strategy could afford various aryl sulfones in 32%~93% yields at room temperature under blue light irradiation. In addition， the application of the strategy in preparation of celecoxib analogue was achieved.
