Nomenclature of Amines
Like most organic functional-group families, amines can be named under either of two systems: an older common-name system (13.2.1), built from the names of the groups attached to nitrogen, and the modern, systematic IUPAC system (13.2.2), built from the corresponding parent alkane or arene name. Table 13.2 works through a representative set of primary, secondary and tertiary amines -- aliphatic and aromatic -- giving both names side by side, so …
Table 13.2 pairs each amine's structure with its common name and its IUPAC name. Primary amines: CH3-NH2, Methylamine, Methanamine. CH3-CH2-CH2-NH2, n-Propylamine, Propan-1-amine. CH3-CH(NH2)-CH3, Isopropylamine, Propan-2-amine. H2N-CH2-CH2-NH2, Ethylenediamine, Ethane-1,2-diamine. CH2=CH-CH2-NH2, Allylamine, Prop-2-en-1-amine. C6H5-NH2, Aniline/Phenylamine, Aniline or Benzenamine. H2N-(CH2)6-NH2, Hexamethylenediamine, Hexane-1,6-diamine. p-CH3-C6H4-NH2, p-Toluidine, 4-Methylaniline. Cyclohexyl-NH2, Cyclohexylamine, Cyclohexanamine. C6H5-CH2-NH2, Benzylamine, Phenylmethanamine. p-Br-C6H4-NH2, p-Bromoaniline, 4-Bromoaniline or 4-Bromobenzenamine. Secondary amines: CH3-NH-CH3, Dimethylamine, N-methylmethanamine. CH3-CH2-NH-CH3, Ethylmethylamine, N-methylethanamine. C6H5-NH-CH3, Methylphenylamine, N-methylaniline or N-methylbenzenamine.
