3 Brief Demonstration of the General Nomenclature Rules
Pyrene-l,3,6,8(2H,7H)-tetrone
Note:
For a number of ketones derived from heterocycles whose names end with
.•. idine and ... oline the abbreviated suffixes ... idone and .•. olone are still
often used instead of the systematic endings ... idinone and ... olinone,
e. g.: pyridone vs. pyrrolidinone, quinolone vs. quinolinone, piperidone vs.
piperidinone, pyrrolidone vs. pyrrolidinone, etc. It is recommended that
proper systematic names are use here too.

Arene-derived di- and tetraketones presenting the typical quinoid double
bond arrangement can be characterized by name suffixes such as
... quinone, ... diquinone etc. the parent name sometimes being subject to
certain changes.

Transcription of these rules for naming thioaldehydes and thioketones
causes no problems as will be demonstrated by just two examples.
