Electrochemical Synthesis of 2-Hydroxy-para-terphenyls by Dehydrogenative Anodic C-C Cross-Coupling Reaction

The anodic C-C cross-coupling reaction provides fast access to a wide range of bi- and terarylic scaffolds by electrochemically mediated arylation reactions. Herein, a metal- and reagent-free electrosynthetic protocol for the synthesis of nonsymmetrical 2-hydroxy- para -teraryl derivatives is presented for the first time. It is scalable, easy to conduct, and allows the use of a broad variety of different functional groups.
