cross‐coupling reaction is a versatile synthetic approach to symmetric and non‐symmetric biphenols and arylated phenols. We herein present a metal‐free electrosynthetic method that provides access to symmetric and non‐symmetric meta‐terphenyl‐2,2′′‐diols in good yields and high selectivity. Symmetric derivatives can be obtained by direct electrolysis in an undivided cell. The synthesis of non‐symmetric
