A novel design-based removable N,O-bidentate directinggroup based on commercially available 4-aminoantipyrine (AAP) is reported. Aromatic benzamides bearing the AAP directinggroup underwent efficient Ru-catalyzed C(sp2)−H bond arylation reactions under mild reaction conditions and using [RuCl2(PPh3)3] as a catalyst. Various differently substituted and electronically different antipyrinyl (AP) benzamides
