Illustrated Glossary of Organic Chemistry

Base promoted: A reaction that requires a base to occur, but is not catalytic in base (i.e., the base is not regenerated in the reaction mechanism).

Deprotonation of a carboxylic acid by strong base (HO-) is promoted by base but not catalyzed by base because the base is not regenerated in the reaction mechanism.


This aldol reaction is catalyzed by base (HO-) because the base is regenerated in the reaction mechanism.
