In recent years, the palladium-catalyzed cross-coupling reaction has evolved as a powerful synthetic tool for the construction of unsymmetrical biaryls. 1 The reaction, which is vastly superior to the classical methods of biaryl synthesis (Gomberg-Bachmann and Ullmann synthesis), 2 usually involves an arylmetal species (ArM) acting upon an aryl electrophile (Ar′ X) in presence of a Pd0 catalyst. Numerous versions of this reaction, featuring ...
