(i)Hofmann’s bromamide reaction: The conversion of a primary amide to a primary amine, containing one carbon atom less than the original amide, on heating with a mixture of${\text{Br}}_2$in presence of$\text{NaOH}$is called Hofmann’s bromide reaction

$\begin{array}{l}{\text{CH}}_{\text{3}}{\text{CONH}}_2+{\text{Br}}_2+4\text{NaOH}\to {\text{CH}}_3{\text{NH}}_2+2\text{NaBr}+{\text{Na}}_2{\text{CO}}_3+2{\text{H}}_{\text{2}}\text{}\text{O}\\ \[ \text{Acetamide} \]\mathrm{Methylamine}\end{array}$

(ii)Gabriel phthalimide reaction:This is a very convenient method for the preparation of pure aliphatic and aryl primary amines.
