Room-temperature ortho-arylation and acetoxylation of anilides have been achieved using cationic palladium (Pd[TFA]+) as catalyst and (NH 4)2S2O8 as oxidant. Preliminary investigation of the mechanism

(Chemical Equation Presented) Various anilides have been directly ortho-acetoxylated through a Pd(OAc)2-catalyzed C-H bond activation process. The amide group in anilides was found to functionalize as an elegant directing group to convert aromatic sp2 C-H bonds into C-O bonds in high regioselectivity with acetic acid as the acetate source and K 2S2O8 as the oxidant.
