It is to be proposed how to carry out the given synthesis, in which an amide isconverted into an acid anhydride. Concept introduction: An acyl substitution that converts an acid derivative from a higher rung onthe stability ladder to one on a lower rung of the ladder is energeticallyfavorable. Therefore, the conversion of the more stable acid derivative to a less stable acid derivative is cannot proceeds in a single step. Thus for the conversion of an amide to an acid anhydride first amide must be converted to acid chloride. Amide on base hydrolysis produces corresponding carboxylic acid . Carboxylic acid on treatment either PCl 3 or SOCl 2 corresponding acid chloride is formed.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
