The mechanism of basic amide hydrolysis is straightforward and recent hydrolysis of amides in dilute acid solutions involves attack by a water molecule.

carboxylic acid promoted amide hydrolysis is presented which involves intermediates of standing of enzyme-catalyzed amide hydrolysis.1'2 Although.
The a-carbon reactions of all carbonyl compounds are grouped together in Chapter 22. The reactivity of amides at nitrogen is discussed in Sec. 23.11D. 21.7.
