We developed a new transient directing group, N-(2-benzoyl-4-chlorophenyl)-1,1,1-trifluoromethanesulfonamide, which can facilitate the γ-monoarylation of free aminescontaining symmetric γ-C–H bonds. A variety of aminescontaining symmetric and identical γ-C(sp3)–H and γ-C(sp2)–H reacted with a diverse range of aryl and heteroaryl iodides to provide γ-monoarylated products exclusively.
