Abstract

Abstract : Herein, a simple Cu-catalyzed system for the synthesis of carbamates has been developed using anilines with diisopropyl azodicarboxylate as a carbonyl source under solvent-free conditions. Abstract : A Cu-catalyzed efficient methodology for the direct carbonylation of anilines has been developed. The N–H bond cleavage and N–C bond formation were notably achieved under solvent-free conditions and a variety of carbamates were synthesized from readily available anilines using diisopropyl azodicarboxylate (DIAD) as the carbonylating source.
