Hofmann bromamide reaction
NettetHofmann rearrangement, also known as Hofmann degradation and not to be confused with Hofmann elimination, is the reaction of a primary amide with a halogen (chlorine or bromine) in strongly basic (sodium or potassium hydroxide) aqueous medium, which converts the amide to a primary amine. NettetThis reaction involves the degradation of amide and is popularly known as Hoffmann bromamide degradation reaction. Thus, the primary amine contains one carbon less than the number of carbon atoms in that amide. RCONH 2 +Br 2 + 4NaOH → R-NH 2 + Na 2 CO 3 + 2NaBr + 2H 2 O.
