Abstrakt: Depending on the character of the substituents and the reaction conditions, the bromination of N-exo-carbamoyl derivatives of sydnoneimines may proceed in the heterocyclic ring and (or) in the phenyl ring of the exocyclic substituent. Nitration proceeds only in the phenyl rings of the substituents.
