A complex generated from iron(III) fluoride and 1,3-bis(2,6-di-i-propylphenyl)imidazolinium chloride catalyzes the reaction of aryl magnesium bromides with aryl chlorides to give the corresponding cross-coupling products, unsymmetrical biaryls, in good to excellent yields. The "fluoride effect" is also remarkably effective for cobalt- and nickel-catalyzed biaryl cross-couplings.
