CHAPTER 18: FUNCTIONAL DERIVATIVES OF

CHAPTER 18: FUNCTIONAL DERIVATIVES OF CARBOXYLIC ACIDS Esters are considered to be functional derivatives of carboxylic acids in which the acidic proton has been replaced by an organic group The synthesis of esters by the acid catalyzed condensation of a carboxylic acid and an alcohol was considered at the end of the previous chapter

Carboxylic Acid Derivatives

Carboxylic Acid Derivatives Amides Esters and Anhydrides These derivatives are formed by a condensation reaction with carboxylic acid in which two molecules combine into one while a small molecule is lost (water in this case) Description Amides General formula of RCONR2 Named by replacing –oic acid with –amide Alkyl substituents on the nitrogen atom are Carboxylic Acid Derivatives

Carboxylic Acids and Derivatives

One final group of carboxylic acid derivatives is the anhydrides In the formation of an anhydride one water molecule is removed and a bond is formed between two carboxylic acid molecules Many anhydrides are cyclic which may result from the intramolecular dehydration of a dicarboxylic acid

Functional Derivatives of Carboxylic Acids

Functional Derivatives of Carboxylic Acids Organic Lecture Series 2222 • There are five classes of organic acid derivatives • Each arises from a dehydration reaction usually a condensation • Therefore each derivative can also be hydrolyzed RC-OH H-Cl H-OR' H-NH 2 O H-OCR' O RC=N HO H RC-OH O RC-OH O RC-OH O-H 2O -H 2O -H 2O -H 2O-H 2O

Carboxylic Acids and Derivatives

Carboxylic acids can exist as aliphatic carboxylic acids aromatic carboxylic acids and thiocarboxylic acids There are wide ranges of carboxylic acid derivatives which include esters amides acid chlorides anhydrides and imides Carboxylic acids can be converted into amines and aldehydes via esters or amides (such as Weinreb amides)

Carboxylic Acids

Carboxylic acids with low molecular weights dissolve in water because the carboxyl group forms several hydrogen bonds with water A carboxylic acid acts both as a hydrogen bond donor through its hydroxyl hydrogen atom and as a hydrogen bond acceptor through the lone pair electrons of both oxygen atoms
