S-oxide
In organosulfur chemistry, S-oxide may refer to:
- S-oxides of disulfides, compounds with the linkage RSSR. Several 1,2-dithiolanes form S-oxides.
- S-oxides of thioketones and thioaldehydes, compounds with the formula R2C=S=O and RCH=S=O, respectively. syn-Propanethial-S-oxide, a lacrymatory component of onion, is one example.
- sulfoxides, compounds with the formula R2SO, are sometimes referred to as S-oxides. Methionine-S-oxide reductase illustrates this nomenclature.
