Abstract

The present invention relates to a novel process for preparing substituted biphenylamides of the general formula (V) characterized in that anilides of the formula (II) in a solvent other than tetrahydrofuran, are reacted with an organoboron compound of the formula (III) in the presence of a catalyst system consisting of a ruthenium catalyst, an activator, an oxidizing agent and a metal triflate.
