A newapproach to the synthesis of fluorinated biaryl compounds from easily available starting materials is described. This protocol is based on the direct palladium-catalyzed desulfitative cross-coupling of polyfluoroarenes with various arylsulfinate salts via CH bond activation, accelerated by trace amount of water. The method allows the synthesis of various fluorinated biaryl products in moderate
