    en.wikipedia.org/wiki/Selenide

    At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental selenium: 2 SeH − + O 2 → 2 Se + 2 OH −. Most elements form selenides. They sometimes have salt-like properties, e.g. sodium selenide, but most exhibit covalent bonding, e.g. molybdenum diselenide. Their properties are diverse ...

    en.wikipedia.org/wiki/Sodium_selenate

    Sodium selenate is the inorganic compound with the formula Na 2 SeO 4. It exists as the anhydrous salt, the heptahydrate, and the decahydrate. [1] These are white, water-soluble solids. The decahydrate is a common ingredient in multivitamins and livestock feed as a source of selenium. The anhydrous salt is used in the production of some glass.

  9. Organoselenium chemistry - Wikipedia

    en.wikipedia.org/wiki/Organoselenium_chemistry

    In presence of a β-hydrogen, a selenide will give an elimination reaction after oxidation, to leave behind an alkene and a SeO-selenoperoxol. The SeO-selenoperoxol is highly reactive and is not isolated as such. In the elimination reaction, all five participating reaction centers are coplanar and, therefore, the reaction stereochemistry is syn.
