在Pd（OAc）（2）/CF_3CO_2H（TFA）/K_2S_2O_8催化体系中，对二甲苯均偶联得到主要产物联芳或二芳甲烷。在该偶联反应中，仅通过调节TFA的浓度就可以选择性地活化对二甲苯的芳基和苄基C-H键。
A homocoupling of p-xylene to afford biaryl- or diarylmethane as a major product has been carried out in a catalytic system of Pd(OAc)(2)/CF3CO2H (TFA)/K2S2O8. In this coupling reaction, the aryl and benzylic C-H bonds of p-xylene can be selectively activated just by tuning the concentration of TFA.
