When sulfides are oxidized at sulfur they transmute into two new compound classes traditionally designated as sulfoxides and sulfones, respectively. Accordingly, the most coherent method for naming individual
members thereof is here exceptionally provided by radicofunctional
nomenclature, since the practical application of substitutive nomenclature to these compounds as found in the registry nomenclature is to the
highest degree incongruent and confusing.
On the one hand, relating simple sulfoxides to the most senior (but
functionally subordinate) hydrocarbon component totally disregards the
high rank of the SO and S02 functions. Polysulfoxides and polysulfones, on
the other hand, continue to be named and indexed as such.

In this context it may be again noted that rigorous application of the existing rules of substitutive nomenclature on the basis of the universal parent
hydride names of Table 14 would lead to solutions of utmost consistency
and simplicity, e.g.:
