Palladium-Catalyzed Dehydrogenative Direct Arylations of 1,2,3-Triazoles

Abstract

Palladium-catalyzed intramolecular dehydrogenative direct arylations of 1,2,3-triazoles were accomplished under ambient pressure of air, which set the stage for a modular synthesis of annulated phenanthrenes through a reaction sequence comprising two distinct catalytic C-H bond functionalization reactions.
