Rh(III)-Catalyzed Oxidative C–2 Coupling of N-Pyridinylindoles with Benzo[b]thiophene 1,1-Dioxides via C–H Bond Activation

An efficient Rh(III)-catalyzed cross-dehydrogenative coupling of N-pyridinylindoles with benzo[b]thiophene 1,1-dioxides has been developed through directing-group-assisted C–H activation. This transformation constructs a new C–C bond from two inert C–H bonds in a one-pot reaction. The present reaction is compatible with various functional groups with respect to indoles and benzothiophene[b] 1,1-dioxides. Furthermore, the emission properties of...
