Zusammenfassung:Preparation of 2-aryl-hydroquinones of formula (I) by oxidizing by an electrochemical route a compound of formula (II): (see fig.II) (see fig.I) wherein A represents an aryl group optionally substituted with groups compatible with the reaction conditions in an acidic aqueous reaction medium, at temperatures within the range of from 10.degree. to 100.degree.C, and with anodes of graphite or PbO2. The products are used in photography and in the field of liquid-crystal polymers.
