Electrochemical formylation of aryl halides by using DMF as a formyl source

Abstract

An electrochemical protocol for the formylation of aryl halides was developed. By using DMF as both a solvent and formyl source, with Ni foam as the cathode and Mg as the sacrificial anode, a series of valuable aromatic aldehydes were obtained in moderate to good yields. This method has features such as very simple and mild reaction conditions, good scalability and a nice substrate scope, which means that it has good application prospects in organic synthesis.
