Specific Classes of Compounds

R-5.5.7 Sulfoxides, sulfones, and their analogues

Compounds with the general structures and are called generically "sulfoxides" and "sulfones", respectively. They may be named substitutively by citing the prefix name of the group followed by "sulfinyl" or "sulfonyl" and the name of the parent hydride corresponding to R. In functional class nomenclature, names are formed by citing the prefix names for the groups R and in alphabetical order as separate words followed by the class name "sulfoxide" or "sulfone", respectively . Selenium and tellurium analogues are named in the same way using prefix names such as "-seleninyl-" and "-selenonyl-", and class names such as "selenoxide" and "selenone".

Examples to R-5.5.7

When a group >SO or >SO2 is part of a ring system, the oxygen atom(s) can be expressed additively by citing the class name "oxide" after the name of the heterocycle, or substitutively by adding "oxo-" prefixes to the name of the heterocycle in which the sulfur atoms are designated as or .
