Beginning in the middle of 2015 we successfully introduced tags for common functional groups. In this discussion it was noted that is rarely used and maybe not such a good tag therefore.[1] Lately was introduced and I thought that this will likely face the same problem. Since we graduated tags with single uses are not automatically culled (iirc), so that is no problem. However, I debate that the tag is actually useful.

Instead I am proposing the creation of a tag that has all kinds of sulfur or just organosulfur compounds as a target.[2]
A very quick search supports that there are enough uses of "thio" in questions to support such a tag.
I am, however, uncertain about the name and a scope. I was originally thinking of , but I could not find it in the goldbook. I thought it would transport the meaning of a sulfur containing compound quite well.
I think that organosulfur is too specific as it would (kind of) exclude thiocyanate.
And just using seems to be just wrong, although the entry for the prefix exists in the gooldbook.

Please go ahead, suggest names, propose scopes, discuss in general.


  1. I suggested then to include thiols in the alcohol tag. I'm not so sure this is a good idea any more.
  2. We would still be keeping and as synonyms.

  • $\begingroup$ The Glossary of class names of organic compounds and reactivity intermediates based on structure (IUPAC Recommendations 1995) mentions thioethers as the former name for sulfides $\ce{RSR}$. $\endgroup$

  • $\begingroup$ +1 for organosulfur-compounds. I edited the thioether tag wiki and mentioned sulfides. $\endgroup$ Commented Jan 4, 2016 at 20:32
  • $\begingroup$ @Geoff The link that Loong gave recommends the use of sulfides instead of thioethers, your edit suggests the opposite. However, if we introduce a new tag, and make the mentioned ones synonym of those, the tag-wiki will become an orphan and vanish. Since it seems to be on the way to consensus, that such a tag will be created any changes to any of the wiki will be lost eventually. (The last part is not 100% true, it just needs mod privileges to find the orphans.) $\endgroup$ Commented Jan 5, 2016 at 4:17
  • $\begingroup$ @Martin-マーチン - I think the tag wiki edit was about 5 minutes of work. I certainly don't care if it vanishes. $\endgroup$ Commented Jan 5, 2016 at 4:56

Editorial Note:
The tag has been created with mappings to and .

Original post follows.


While thiols and thoethers already exist, this tag can cover a wide range of other compounds, including:

  • Thioesters
  • Thioureas
  • Xanthates
  • Thioacetals
  • Sulfoxides
  • Sulfones
  • Sulfolanes
  • Sulfonic acids
  • Sulfinic acids
  • Disulfides
  • You get the idea

Most of these functional groups are not as common as their analogs, so having individual tags for each is counterproductive.

    $\begingroup$ What about thiocyanates or thiosulfates, they would not be covered. Do you think they should not be covered in this tag? $\endgroup$ Commented Jan 5, 2016 at 4:06

    $\begingroup$ @Martin-マーチン - Can you find a thiosulfate question that really cries out for such a tag? $\endgroup$ Commented Jan 5, 2016 at 4:57
  • $\begingroup$ @Geoff I don't know. I'm not sure. I also have not properly checked. We included inorganic esters in esters, so I just wanted to clarify that point before we go ahead and introduce the tag. $\endgroup$ Commented Jan 5, 2016 at 5:13
