Abstract
An electrochemical method for C—C coupling a phenol and an aniline in a reaction vessel containing a suitable solvent or solvent mixture and a conductive salt to produce biaryls having both hydroxyl and amino functions, wherein the difference in the oxidation potentials ΔE of the substrates ranges from 10 mV to 450 mV and the substrate with the highest oxidation potential is in excess, which method dispenses with multi-step syntheses using metallic reagents.
