atom-economical and good regioselective method for the synthesis of benzoin bis-ethers has been developed via directly using readily available alkynes and alcohols as raw materials under visible light irradiation. The protocol utilizes commercial Mes-Acr+ClO4− as an organophotoredox catalyst and air (O2) as a green sustainable reagent. A range of benzoin bis-ether derivatives were easily and efficiently obtained
