Rh-Catalyzed regioselective C–H activation and C–C bond formation: synthesis and photophysical studies of indazolo[2,3-a]quinolines

Abstract

Rh(III)-Catalyzed regioselective C–H functionalization of 2-aryl-2H-indazoles with alkynes is reported to furnish indazoloquinolines utilizing Cu(OAc)2·H2O as an oxidant, which facilitates the reductive elimination step. Kinetic isotope studies suggest that C–H activation is presumably the product determining step. The products display a strong blue emission with high quantum yields.
