Thioaldehydes, Thioketones, and Thioacetals

Thioketones Rule C-532

532.1 - The suffix "thione" is used to signify the presence of =S at a non-terminal carbon atom.

Examples to Rule C-532.1

532.2 - Names of thiones formed by placing the syllables "thio-" before the name of the corresponding ketone are retained for thio analogues of ketones having accepted non-systematic names, but the nomenclature of the preceding Rule (C-532.1) is in general preferred.

Examples to Rule C-532.2

532.3 - Where a prefix is needed for naming =S in a thioketone, the prefix "thioxo-" is used.

Examples to Rule C-532.3

532.4 - In radicofunctional nomenclature, compounds are named by use of the functional class name "thioketone"

Example to Rule C-532.4
