HAT‐Mediated Electrochemical Cross Dehydrogenative Coupling Reaction of Quinoxalin‐2(1H)‐ones with Ethers

Abstract Herein, a method about hydrogen atom transfer (HAT) mediated electrochemical cross dehydrogenative coupling (CDC) reaction of heterocycles with ethers has been established. Saturated linear, branched or cyclic ethers were all suitable for this cross‐coupling reaction to form the corresponding products in 70–98% yields. The advantages of this reaction are transition metal‐ and chemical oxidant‐free conditions, high yields, and broad functional group tolerance, etc.
