Amides whose nitrogen atom is part of a ring are generally regarded as
acylated heterocycles, subordinate groups gaining preference only when
attached to the same ring.

For lactams and similar compounds in most cases the conventional trivial
names of Table 8 are applied although here too heterocyclic nomenclature
would render much more uniform names possible.

Imines form the functional compound class of lowest rank and are
hence named as such only when no N-organyl substituents are present;
otherwise they are named as ... ylidenamines. If more senior functions are to be respected ... imino prefixes are used. Totally systematic
azane-based names would again bring about considerable simplifications.
