(1a–e) were derived from their corresponding carboxylic acids and bidentate directing groups. These compounds were then used as substrates to investigate the arylation and successive arylation/intramolecular amidation of the γ-C(sp3)–H bonds. The γ-C(sp3)–H arylation arose from the Pd(II)-catalyzed reactions of these compounds with aryl iodides with reaction periods of 4–24 h (except a few reactions
