ChemInform Abstract: Eosin Y Catalyzed Difunctionalization of Styrenes Using O<sub>2sub> and CS<sub>2sub>: A Direct Access to 1,3-Oxathiolane-2-thiones.
The highly regioselective one-pot synthesis of oxathioles is promoted by visible light using eosin Y as organophotoredox catalyst and air as sustainable reagent.
