Electrochemical Synthesis of Selenium‐substituted Benzoxazine via Radical Initiated Cyclization

Abstract 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.
