Carboxylic derivative reactivity
WebThe a-carbon reactions of all carbonyl compounds are grouped together in Chapter 22. The reactivity of amides at nitrogen is discussed in Sec. 23.11D. 21.7 HYDROLYSIS OF CARBOXYLIC ACID DERIVATIVES All carboxylic acid derivatives have in common the fact that they undergo hydrolysis (a cleav-age reaction with water) to yield carboxylic … WebSep 4, 2014 · The reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. The pH for reactions which form imine compounds must be carefully …

WebSep 12, 2024 · Thus successful reactions between amines and carboxylic acid derivatives need to overcome the rather low reactivity of the carbonyl carbon in these compounds. One very good way to do this is to put a very good leaving group in the carboxylic acid derivative. This is what is done with acyl chlorides.
