Synthesis of Carbazoles from 2‐Iodobiphenyls by Palladium‐Catalyzed C−H Activation and Amination with Diaziridinone

Abstract

Abstract A facile and efficient approach has been developed for the synthesis of carbazoles from 2‐iodobiphenyls and diaziridinone under palladium catalysis. A wide range of carbazoles were synthesized in good to excellent yields, and indole derivatives were obtained by using styrenes as the substrate. The palladacycles obtained from 2‐iodobiphenyls acted as the key intermediate, and the reaction should proceed via a tandem Pd‐catalyzed C−H activation/dual C−N bond formation sequence. magnified image
