A highly efficientone-pot synthesis of carbamoyl azides from haloarenes and sodium azide has been developed. The protocol involves palladium-catalysed azidocarbonylation of haloarenes utilizing N -formylsaccharin as a CO source to form acyl azides, which undergo in situ Curtiusrearrangement to afford the desired carbamoyl azides. N -Formylsaccharin is an easy-to-handle solid alternative to CO gas
