NettetTherefore, NaOBr is a reagent for Hoffmann bromamide degradation that is prepared in situ by the reaction between bromine and aqueous sodium hydroxide. The chemical reaction can be depicted as: Br 2 + 2 NaOH → NaBr + NaOBr + H 2 O; Thus, the product of the reaction between CH 3 CONH 2 and NaOBr is methenamine C H 3 N H 2. NettetHoffmann's bromamide reaction involves the conversion of a carboxylic acid amide into an amine with a loss of carbon atom. On treatment with aqueous sodium hypobromite, this Hoffmann's reaction results in the shortening of a carbon chain. Which of the following will not give Hoffmann bromamide reaction?
