    Abstract: The invention relates to a method for the electrolytic oxidative alkoxylating cleavage of 1,2-diarylethane derivatives by electrolytically oxidizing the respective 1,2-diarylethane derivative in a solvent containing the alcohol required for alkoxylation, electrolytic oxidation being performed on a diamond electrode. The inventive method makes it possible to especially produce diaryl derivatives when a 1,2-diarylethane derivative in which the two aryl radicals are directly bonded to each other is used as a substrate.

    Abstract: The invention relates to a method for producing biarylalcohols by means of the electrodimerisation of arylalcohols, said method comprising the following steps: a) an aryloxy compound of the alcohol to be coupled is produced with an element from the group B and Al; b) the aryloxy compounds obtained in a) are electrolytically oxidised and coupled to form the corresponding biaryl derivatives; and c) the desired biaryl alcohols are released. The inventive method enables the dimerisation of arylalcohols with a high degree of selectivity in order to obtain an ortho product.
