题目：Rhodium(III)-Catalyzed C-H Activation and Functionalization of Arenes
Abstract: Metal-catalyzed C-H activation has been widely established as an important strategy in the functionalization of sp2 hybridized C-H bonds. In our studies, under oxidative or redox-neutral conditions, stable rhodium(III) complexes have been successfully applied to the C-H activation of arenes and olefins in the coupling with substrates such as alkenes, alkynes, strained rings, metal salts, and electrophilic amidating reagents. In these C-C and C-N coupling reactions, Rh(III) catalysis has allowed the functionalization of a broad scope of arenes bearing a chelating group with high reactivity, broad substrate scope, and high functional group compatibility. The scope, selectivity, and mechanism of these reactions are discussed.
