An interesting palladium-catalyzedcarbonylativesynthesis of amides from aryltriazenes has been developed. By using Pd(MeCN2)Cl2 as the catalyst precursor under CO pressure via N2 extrusion/CO insertion sequence, broad range of aryltriazenes were transformed into the corresponding amides in good yields with excellent functional groups tolerance. Remarkably, no additives such as acid or phosphine ligand
