Palladium‐Catalyzed Carbonylative Synthesis of Amides from Aryltriazenes under Additive‐Free Conditions

Abstract

An interesting palladium‐catalyzed carbonylative synthesis of amides from aryltriazenes was developed. By using Pd(MeCN2)Cl2 as the catalyst precursor under CO pressure through a N2 extrusion/CO insertion sequence, a broad range of aryltriazenes were transformed into the corresponding amides in good yields with excellent functional group tolerance. Remarkably, no additives such as acids or phosphine ligands were required.
