Direct Anodic Dehydrogenative Cross‐ and Homo‐Coupling of Formanilides

Abstract

Abstract The direct anodic dehydrogenative C−C cross‐ and homo‐coupling of formanilides is reported. This exceptional electrochemical synthesis allows one to prepare a broad variety of non‐symmetrical and symmetrical 2,2′‐diformamidobiphenyls as well as 2‐formamido‐2′‐amidobiphenyls. By applying an easy and simple to perform metal‐ and oxidizer‐free electrochemical protocol, and the formyl group as a highly atom‐economic amino‐protecting group, an important contribution to a sustainable and green‐minded chemistry was achieved.
