4-Aminobenzotriazole directed palladium-catalyzed C–H acetoxylation and intramolecular amination reaction.

We present an approach for ortho C(sp2)-H acylation and intramolecular amination reactions, employing 4-amino-benzotriazole (ABTA) as a bidentate directing group. This method is facilitated by a palladium catalyst in combination with iodobenzene diacetate. Our approach efficiently yields acetoxylation and intramolecular amination products from a variety of acylamide substrates, including arylcarboxamides and arylacetamides. [Display omitted] • Utilize a novel directing group (ABTA). • Effectively activate both C(sp2)-H and C(sp3)-H bonds. • Good yield and selectivity to obtain acetoxylation and intramolecular amination products. • ABTA directing group was removed easily.
