Nomenclature of Organic Chemistry IUPAC Recommendations and
Substitution of amides is expressed by prefixes; numerical N and N′ locants are used as required N-Substitution of amides follows the substitution rules for carboxylic acids described in P-65 1 2 4 Examples: 3-chloropropanamide (PIN) (not 3-chloropropionamide; no substitution on propionamide) 4-chloro-NN-dimethylbutanamide (PIN) |

Organic Chemistry II / CHEM 252 Chapter 20 – Amines
Nomenclature Primary amines are named in systematic (IUPAC) nomenclature by replacing the -e of the corresponding parent alkane with -amine In common nomenclature they are named as alkylamines Simple secondary and tertiary amines are named in common nomenclature by designating the organic groups separately in front of the word amine |

• Learn to recognize the amine and amide functional groups • Learn the IUPAC system for naming amines and amides • Learn the important physical properties of the amines and amides • Learn the major chemical reactions of amines and amides and learn how to predict the products of amide synthesis and hydrolysis reactions |

Naming Amines and Amides (rules)
Amides Classification of amides by the number of alkyl chains: Amides are named as alkanamides IUPAC replaces –oic acid ending with –amide Common names replace -ic acid ending with –amide O Methanamide (IUPAC) H—C—NH2 Formamide (common) O |
How are amides ranked in IUPAC nomenclature?
Preferred IUPAC names for these two acids and their derivatives are formed systematically. Amides are ranked in the same way as the corresponding acids (see P-42). Thus, in substitutive nomenclature, amides from carboxylic acids, including formamide, are senior to urea.
Are amines and amides the same?
Amines and amides come from ammonia (replacing the H’s). Are named as alkylamines. List the names of the alkyl groups bonded to the N atom in alphabetical order in front of amine. CH3 Amines are named as alkanamines. The –e in the alkane name of the longest chain is changed to –amine.
What are amides called?
Amides are named as alkanamides. IUPAC replaces –oic acid ending with –amide. Common names replace -ic acid ending with –amide. An alkyl group bonded to the N atom is named as N-alkyl in front of the amide name. H H • The amide of benzene is named benzamide.
What naming conventions should be used for secondary and tertiary amides?
There are special naming conventions that need to be used for secondary and tertiary amides. Primary amides follow similar naming conventions to other functional groups. Secondary and tertiary amides use an italicised ‘N-‘ to locate the side chains in relation to the amide group.
