acetic anhydride to acetic acid mechanism
If acetic anhydride is used instead of acetic acid, the reaction is much faster and has a higher yield (since acetic anhydride is much more reactive than acetic acid).
What is the mechanism of the reaction between acetic anhydride and alcohol?
The mechanism involves four steps-nucleophilic attack by alcohol, deprotonation by pyridine, leaving group removal and protonation of carboxylate.
When acetic anhydride reacts with alcohol, it does not produce two molecules of ester, but an ester and ethanoic acid.
What does acetic anhydride do in a acetylation reaction?
For this reason, acetic anhydride is often used.
It allows an acetyl group to be added, with a relatively stable leaving group.
