19.2 : 第一級アミンの命名法

Common nomenclature of primary amines is derived by adding -amine as a suffix to the alkyl substituent to give alkylamine.

The IUPAC nomenclature of primary amines is derived by replacing the final -e of the parent alkane with the suffix -amine to give alkanamines. 

If a molecule bears two –NH₂ groups, the final -e of the alkane is retained, and the parent name is suffixed with -diamine.

To use the IUPAC nomenclature, select the longest parent hydrocarbon chain bonded to the amine nitrogen. Then assign the lowest locant to the carbon atom bearing the amine nitrogen.

The substituents and their locant values are listed alphabetically and prefixed to the parent name. Prefixes di- or tri- are used to indicate identical substituents.

Chiral centers, if present, are specified at the beginning of the name.

If a molecule bears another functional group, except halogens, the –NH₂ group is treated as a substituent and prefixed to the parent name.

Primary amines bearing cyclic alkyl groups are named cycloalkylamines or cycloalkanamines.
