Abstract: Rhodium(III)-catalyzed C-H activation-based arylation of sterically hindered (hetero)arenes has been realized using diazo compounds and triazoles as arylating reagents for atroposelective synthesis of two classes of biaryls. The coupling of 3-substituted indoles and N-sulfonyltriazoles afforded… read more here.

Abstract: Direct C–H arylation of nonacidic C(sp2)–H bonds with primary amides as arylating reagents via highly chemoselective C–H/C–N/C–C cleavages has been accomplished for the first time. The key to the success is the cooperative combination of… read more here.
