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.

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. dgworkforce

The least stable alkene (the one with the least number of substituents on the carbons of the double bond), called the Hofmann product, is formed.

"Nettet13. aug. 2024 · I understand that tert-butoxide is used to favor the Hofmann product in elimination reactions due to its steric bulk (and thus inability to abstract a proton in a more substituted position); however, I have often seen proposed organic synthesis involving the use of tert-butoxide when it is seemingly irrelevant.
