Nettet7. apr. 2024 · Hoffmann bromamide degradation reaction can be written as follows – R-CO-NH2 + Br2 + 4NaOH → R-NH2 + Na2CO3 + 2NaBr + 2H2O (General amide) … The Hofmann rearrangement (Hofmann degradation) is the organic reaction of a primary amide to a primary amine with one fewer carbon atom. The reaction involves oxidation of the nitrogen followed by rearrangement of the carbonyl and nitrogen to give an isocyanate intermediate. The reaction can form a wide range of products, including alkyl and aryl amines.
