    en.wikipedia.org/wiki/Selenium_compounds

    The sulfoxide in sulfur chemistry is represented in selenium chemistry by the selenoxides (formula RSe(O)R), which are intermediates in organic synthesis, as illustrated by the selenoxide elimination reaction. Consistent with trends indicated by the double bond rule, selenoketones, R(C=Se)R, and selenaldehydes, R(C=Se)H, are rarely observed.

  4. Sulfoxide - Wikipedia

    en.wikipedia.org/wiki/Sulfoxide

    In organic chemistry, a sulfoxide, also called a sulphoxide, is an organosulfur compound containing a sulfinyl (>SO) functional group attached to two carbon atoms. It is a polar functional group. Sulfoxides are oxidized derivatives of sulfides .

    The simplest sulfoxide, dimethyl sulfoxide, is a common solvent; a common sulfone is sulfolane. Sulfonic acids are used in many detergents. Compounds with carbon–sulfur multiple bonds are uncommon, an exception being carbon disulfide , a volatile colorless liquid that is structurally similar to carbon dioxide.

    en.wikipedia.org/wiki/Organoselenium_chemistry

    [1] [2] [3] Selenium belongs with oxygen and sulfur to the group 16 elements or chalcogens, and similarities in chemistry are to be expected. Organoselenium compounds are found at trace levels in ambient waters, soils and sediments. [4] Selenium can exist with oxidation state −2, +2, +4, +6. Se(II) is the dominant form in organoselenium ...

    Selenium disulfide, also known as selenium sulfide, is a chemical compound and medication used to treat seborrheic dermatitis, dandruff, and pityriasis versicolor. [ 1 ] [ 2 ] It is applied to the affected area as a lotion or shampoo. [ 3 ]

  9. Selenite (ion) - Wikipedia

    en.wikipedia.org/wiki/Selenite_(ion)

    Selenite refers to the anion with the chemical formula Se O 2− 3. It is the oxyanion of selenium. It is the selenium analog of the sulfite ion, SO 2− 3. Thus selenite is pyramidal and selenium is assigned oxidation state +4. Selenite also refers to compounds that contains this ion, for example sodium selenite Na 2 SeO 3 which is a common ...
