An efficient iodine-mediated electrochemical C(sp3)-H cyclization was developed under mild conditions. A variety of functionalized quinoxalines can be obtained with good to excellent yields by virtue of this method. The reaction features a broad substrate scope, the regulation of product distribution, scalable preparation and high atomic economy. The reaction mechanism was investigated in detail.
