Research Progress in Electrochemical Halogenation

Organic electrochemical synthesis is considered to be an environmentally benign, highly effective and versatile synthesis method, which is often used to construct carbon-carbon and carbon-heteroatom bonds. Such methods can often avoid the use of transition metal catalysts and expensive oxidants, which is in line with the concept of “green chemistry”. Halogenation plays an important role in organic synthesis. In recent years, electrochemical halogenation has made great progress. In this paper, the existing studies on electrochemical halogenation are collected and summarized.
