Formation of unsymmetrical biaryls from simple arenes has been achieved successfully in a catalytic system of Pd(OAc) 2 /CF 3 CO 2 H(TFA)/K 2 S 2 O 8 just by tuning the concentrations of arenes and TFA under mild conditions. A proposed mechanism containing two-step aromatic C−H activation on this novel intermolecular cross-coupling of arenes is also suggested and partly supported by experiments.
