In the presence of aminepentacarbonyltungsten, base, and a catalytic amount of palladium(0) complex, carbamoylation of aryl halide proceeds to afford amide. The reaction may involve transmetalation between palladium(II) intermediate and carbamoyltungstenate that is generated in situ. This catalytic cross-coupling reaction provides an alternative method to the conventional palladium-catalyzed amidation
