Abstract
A new solvent/ligand-controlled switchable C–H arylation of 1-methyl-4-nitro-1 H -indazole catalyzed by Pd(OAc)2 was achieved. A bidentate ligand in DMA promoted the activation at C7 position, while a phosphine ligand in H2 O oriented the arylation at C3 position. The C3 and C7 arylation products were obtained in moderate to good yields and with high regioselectivity. [ABSTRACT FROM AUTHOR]
