The ruthenium(II)-catalyzed ortho-C−H arylation of 2-aroyl-imidazoles with aryl bromides and chloride is reported. An imidazole ring functions both as a masked ester and a directing group for C−H activation. A variety of functional groups are tolerated under the reaction conditions. The arylated final products could be easily converted into the corresponding esters and amide.
