Aryl Grignard reagents react with phenyl tosylate in uncatalyzed and Cu(I) catalyzed reactions to give sulfones, which react further with Grignard reagents to give biaryls as sole or coproducts. The outcome of the reaction depends mainly on variations in the structure of the Grignard reagent. Phenyl and p-tolyl Grignard reagents give sulfones, but p-anisyl Grignard reagent gives biaryl as main product in moderate yields.
