Electrochemical Synthesis of Selenium‐substituted Benzoxazine via Radical Initiated Cyclization

A strategy for electrochemically synthesizing selenium benzoxazines through o‐vinylaniline and diselenide has been developed. This metal‐free and oxidant‐free electrochemical synthesis method is carried out in an undivided cell under mild conditions, which is more environmentally friendly. Moreover, a variety of selenium‐substituted benzoxazine can be prepared in good yield with a broad scope and functional group tolerance, which has potential industrial application value. A metal‐free and oxidant‐free green strategy for the electrochemical synthesis of benzoxazine selenium by o‐vinylaniline and diselenide is reported.
