Primary amide to amine
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. WebAcid Cl + Amine. The reaction of acid chlorides and amines to form amides is very general. Typically the reaction takes place at RT with a suitable base (ex. TEA or DIEA) in an …
