Acyl isocyanates generated by the reaction of primary amides with oxalyl chloride react with a wide range of amides, hydrazides, amines, alcohols, carbazate, and sulfonate to provide symmetrical and unsymmetrical diacyl urea derivatives, acyl ureas/carbamates/thiocarbamates, and related compounds. This convenient one-pot, two-step synthesis uses cheap and commercially available starting reagents.
