Cover Picture Nicholas E. Leadbeater* and Maria Marco Biaryl compounds can be prepared in an aqueous Suzuki-type coupling reaction without the need for a transition-metal catalyst. The Suzuki coupling reaction (palladium-catalyzed coupling of aryl halides with boronic acids) has virtually become the method of choice for the synthesis of biaryl compounds. Under the right conditions, however, it is possible to perform catalyst-free Suzuki-type couplings. Further details are reported in the Communication by N. E. Leadbeater and M. Marco on page 1407 ff.
