Electrochemical process for the coupling of phenol with aniline

摘要

Electrochemical process for the coupling of phenol with aniline comprising the process steps: a '') filling a solvent or solvent mixture and a conductive salt, in a reaction vessel, b '') adding an aniline having an oxidation potential EOx1 in the reaction vessel, c '') adding a Phenol having an oxidation potential EOx2 in the reaction vessel, wherein: EOx2 EOx1 and EOx2 - EOx1 = ΔE, wherein the phenol is added in excess to the aniline, and the solvent or solvent mixture is selected such that ΔE in the range of 10 mV to 450 mV, d '') introducing two electrodes into the reaction solution, e '') applying a voltage to the electrodes, f '') coupling of the phenol and the aniline.
