Abstract

A highly efficient one-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 Curtius rearrangement to afford the desired carbamoyl azides. N-Formylsaccharin is an easy-to-handle solid alternative to CO gas.
