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.

Examples to Rule C-621.1

see Rules C-641.1 and C-641.7 and Table XII)

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 ".
