(f)The starting material is a cyclic anhydride. Acid anhydrides react with water to yield two car-boxylic acid functions; when the anhydride is cyclic, a dicarboxylic acid results.(g)In dilute sodium hydroxide the anhydride is converted to the disodium salt of the diacid.(h)One of the carbonyl groups of the cyclic anhydride is converted to an amide function on reac-tion with ammonia. The other, the one that would become a carboxylic acid group, is con-verted to an ammonium carboxylate salt.(i)Acid anhydrides are used as acylating agents in Friedel–Crafts reactions.(j)The reactant is maleic anhydride; it is a good dienophile in Diels–Alder reactions.(k)Acid anhydrides react with alcohols to give an ester and a carboxylic acid.
