Groups Containing One Nitrogen Atom
Amines Rule C-811 General 811.1 - Bases in which nitrogen forms part of a ring are named as heterocyclic compounds in accordance with Section B of
these Rules. The termination "-ine", "-ole", or "-ete" of such names is not considered to be a suffix in the sense of Rule C-10.3, and so may be followed by
endings to denote a substituent of the heterocycle, as, for example, in 2-quinolinol (I) or 4-thiazolecarboxylic acid (II). However, the endings denoting quaternary atoms (see Rule C-816)
are considered as suffixes, and substituents must then be named by prefixes, as, for example, in 2-carboxypyridinium chloride (III). In the same way as "-ium" the ending "-amine" (see below) is
considered as a suffix.
811.2 - The generic name "amine'' is applied to compounds NH2R, , and , which are called primary, secondary, and
tertiary amines, respectively. In a wider sense, compounds containing nitrogen in a ring and owing their basicity to this atom may also be referred to as "amines".
811.3 - An -NH2 group, when not the principal group, is named by the prefix "amino-".
Note: In Beilstein's Handbuch der organischen Chemie use of the prefix "amino-" is permitted as an alternative, when -NH2 is the principal group, but this method is not recommended
here; it leads to names such as 1-aminobutane, 2-aminopentane, and 1-aminoanthracene.
Examples to Rule C-811.3
811.4 - Radicals RNH-, R2N-, and are named as substituted amino groups by changing "ine'' of the amine to "ino".
The following are examples of trivial names which are retained:
