The use of a simple undivided cell with carbon electrodes enables an efficient and practical electrochemical reduction of cyclic imides at room temperature to provide hydroxylactams and lactams in a controllable manner, tuned by electric current and reaction time. The reaction exhibits broad substrate scope and high functional group tolerance.
