Decarboxylation - an overview | ScienceDirect Topics

Decarboxylation - an overview | ScienceDirect Topics

Decarboxylation begins with an internal acid-base reaction, where the acid is the O H unit of the carboxylic acid, and the base is the oxygen of the carbonyl β to the acid moiety. Decarboxylation is possible because of the facile loss of a neutral leaving group carbon dioxide.
