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.
