通过在催化性Pd(OAc)2和K 2 S 2 O 8作为氧化剂的存在下,通过对苯甲酸酯的芳基邻-sp 2 C-H键进行氧化偶联,成功地完成了2,2'-双苯胺的制备。在室温(25°C)下在MsOH / CF 3 CO 2 H(TFA)中溶解。在这些偶联反应中,被各种给电子或吸电子基团取代的苯甲酸酯的芳环是可容忍的。

The preparation of secondary 2,2′-bisanilides has been successfully achieved through an oxidative coupling of aryl ortho-sp2 C–H bonds of anilides in the presence of catalytic Pd(OAc)2 and K2S2O8 as an oxidant in MsOH/CF3CO2H (TFA) at roomtemperature (25 °C). The aromatic rings of anilides substituted by various electron-donating or electron-withdrawing groups are tolerant in these coupling reactions
