A Convenient Synthesis of Sulfones via Light Promoted Coupling of Sodium Sulfinates and Aryl Halides

Abstract A convenient and efficient synthesis of sulfones from sulfinates and aryl halides was developed. The reaction occurred under UV irradiation without transition metal catalyst or photocatalyst. A radical pathway via single‐electron transfer (SET) of electron donor‐acceptor (EDA) complex was proposed based on UV‐vis spectroscopy, radical inhibiting and trapping experiments. magnified image
