Question

How can a carboxylic acid be converted to an amine having one carbon atom less than the carboxyl acid used?

Solution

The reaction of the carboxylic acid with ammonia gives amide. which on Hoffman reaction gives amine.
In this reaction, migration of an alkyl or aryl group takes place from carbonyl carbon of the amide to the nitrogen atom. The amine so formed contains one carbon less than that present in the amide.
