2-Aminophenyl-1H-pyrazole was discovered as a removable, bidentate directing group for copper-mediated aerobic oxidative sp 2 C–H bond chlorination employing trichloroacetamide as a new chlorine source. When Cu(OAc)2 was employed as the copper source, 1,1,3,3-­tetramethylguanidine (TMG) as an organic base, the reaction, optimally carried out overnight in DMSO at 80 °C in open air, produced a variety of mono- and dichlorinated products in moderate to excellent yields. This directing group can be removed oxidatively with cerium ammonium nitrate (CAN).
