Hoffmann bromamide reaction involves conversion of a carboxylic acid amide into an amine with a loss of a carbon
P
atom on treatment with aqueous sodium hypobromite. Thus Hoffmann result in shortening of a carbon chain.
Mechanism of the reaction is:
(A) Product \( \mathrm{A} \) is (Major)
(1) \( \mathrm{Ph}-\mathrm{NH}_{2} \)
(2) \( \mathrm{Ph}-\mathrm{CH}_{2}-\mathrm{NH}_{2} \)
(3) \( \mathrm{P}-\mathrm{NH}-\mathrm{CH}_{3} \)
(4)
