Abstract

Electro-oxidation enables a practical and sustainable synthesis of arylsulfonate from stable and readily available phenols and sodium arenesulfinates as the starting materials. The reaction takes place under mild reaction conditions without additional oxidants. A wide range of arylsulfonate esters were produced in good to excellent yields.
