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 K2S2O8 as the oxidant.
