Thiols and Related Compounds

Sulfides Rule C-514

514.1 - Compounds have the generic name "sulfides" Specifically they are named analogously to ethers, in substitutive nomenclature with "alkylthio-" or "arylthio-", etc., in place of "alkyloxy-", etc., in radicofunctional nomenclature with "sulfide" in place of "ether" or "oxide", and for assemblies of identical units with "thio-" in place of "oxy-".

Examples to Rule C-514.1

514.2 - When nomenclature according to Rule C-514.1 becomes complex, as, for example, when several sulfur atoms are present in an acyclic compound, replacement nomenclature can be used (see Subsection C-0.6).

Example to Rule C-514.2

514.3 - Cyclic sulfides are named by the following methods: (a) by prefixing "thia-" to the name of the parent carbocyclic compound; (b) by using an extension of the Hantzsch-Widman method (Rule B-1); or (c) by trivial or semitrivial names for cyclic sulfur compounds set out in Rule B-2.11.

Examples to Rule C-514.3

514.4 - A sulfur atom directly attached to two carbon atoms already forming part of a ring, or to two adjacent carbon atoms in a chain, may be indicated (a) by the prefix "epithio" or (b) by means of Rule C-514.3(a).

Examples to Rule C-514.4
