Electrochemical Selenylation of Alkynyl Aryl Ketones: Efficient Synthesis of 3‐Selenylated Chromones under Catalyst‐ and Chemical‐Oxidant‐Free Conditions

Abstract An electrochemical synthesis of various 3‐selenylated chromones via selenylation of alkynyl aryl ketones without the employment of catalyst and chemical‐oxidant is described here. This method features mild conditions, high efficiency, and wide substrate scope. Furthermore, the scale‐up reaction runs smoothly which indicates the practicability of this electrosynthesis strategy.
