The Pd-catalyzed direct C(sp2)–H arylation of aromatic ketones using a transient directing group is described. The ketimine/carboxylate bidentate directing group in situ generated from aromatic ketone and glycine enabled a palladium-catalyzed ortho-C–H arylation, which shows extensive substrate compatibility.
