The direct oxidative cross‐coupling of phenols is a very challenging transformation, as homo‐coupling is usually strongly preferred. Electrochemical methods circumvent the use of oxidizing reagents or metal catalysts and are therefore highly attractive. Employing electrolytes with a high capacity for hydrogen bonding, such as methanol with formic acid or 1,1,1,3,3,3‐hexafluoro‐2‐propanol, a direct
