A convenient and efficient palladium-catalyzed synthesis of aromatic ketones and isoindolobenzimidazoles has been developed via selective aromatic CH bond acylation. The protocol uses palladium acetate as the catalyst, readily available carboxylicacids as the acylating reagents, trifluoroacetic anhydride as the activated agent of the acids, and the corresponding aromatic ketones and isoindolobenzimidazoles

An efficient method was developed for the direct acylation of arene sp2 C−H bonds with alcohols using palladium chloride as a catalyst and peroxide as the oxidant. The alcohols were oxidized to their corresponding aldehydes in situ and efficiently coupled with 2-arylpyridines to give aryl ketones in chlorobenzene.
