WebAcid-catalyzed enolization involves the conjugate acid of the carbonyl compound. Recall that this ion is also a carbocation (Sec. 19.6). Loss of the proton from oxygen gives back the starting carbonyl compound; loss of the proton from the a-carbon gives the enol. An enol and its carbonyl isomer have the same conjugate acid.

WebChapter 9: A return to the carbonyl. As we have seen carbonyl compounds undergo both acid and base catalyzed reactions involving nucleophilic attack at the carbonyl carbon (or at the beta carbon of conjugated carbonyls). This reaction, in its many guises, can produce an impressive range of products from the formation of an ester from an acid to ...
