在Pd（OAc）（2）/CF_3CO_2H（TFA）/K_2S_2O_8催化体系中，通过调节芳烃和TFA的浓度，在温和的条件下成功地实现了简单芳烃合成不对称联芳基化合物。提出了芳烃分子间交叉偶联反应的两步芳烃C-H活化机理，并得到了实验的部分支持。
Formation of unsymmetrical biaryls from simple arenes has been achieved successfully in a catalytic system of Pd(OAc)(2)/CF3CO2H(TFA)/K2S2O8 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.
