Sulfoxides, Sulfones, and Sulfur Acids
Organosulfur Halides Rule C-621 621.1 - Compounds in which sulfur is directly linked only to an organic radical and to halogen atoms are named by attaching the name of
the radical in front of the word "sulfur" and then stating, as a separate word (or words), the number and name(s) of the halide.
621.2 - When in the compounds described in the preceding Rule the organic radical contains also a substituent to be named as principal group, a composite prefix is formed for the
halogenosulfur group by attaching the number and substitutive name(s) of the halogen atoms (see Rule C-102) in front of the syllable "thio ".
