Ethanoic propionic anhydride
Webanhydride to prepare an ester or amide wastes one equivalent of the parent acid as a leaving group. (For example, acetic acid is a by-product in Eqs. 21.40 and 21.41.) Therefore, this re-action in practice is used only with inexpensive and readily available anhydrides, such as acetic anhydride.
