  2. Sodium selenide - Wikipedia

    en.wikipedia.org/wiki/Sodium_selenide

    Sodium selenide is an inorganic compound of sodium and selenium with the chemical formula Na 2 Se. Preparation. This colourless solid is prepared by the reaction of ...

  3. Selenide - Wikipedia

    en.wikipedia.org/wiki/Selenide

    Sample of cadmium selenide, a pigment. The parent inorganic selenide is hydrogen selenide (H 2 Se). It is a colorless, malodorous, toxic gas. It dissolves in aqueous solution, to give the hydrogenselenide or biselenide ion HSe −. At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental ...

  4. Selenoxide elimination - Wikipedia

    en.wikipedia.org/wiki/Selenoxide_elimination

    Sodium benzeneselenolate; Trimethylsilyl phenyl selenide; The most common oxidizing agent employed is hydrogen peroxide (H 2 O 2). [9] It is sometimes used in excess, to overcome catalytic decomposition of H 2 O 2 by selenium; however, undesired oxidation of starting material has been observed under these conditions.

    en.wikipedia.org/wiki/Selenium_compounds

    The selenide dianion Se 2− forms a variety of compounds, including the minerals from which selenium is obtained commercially. Illustrative selenides include mercury selenide (HgSe), lead selenide (PbSe), zinc selenide (ZnSe), and copper indium gallium diselenide (Cu(Ga,In)Se 2). These materials are semiconductors.

  6. 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.

  7. Diphenyl diselenide - Wikipedia

    en.wikipedia.org/wiki/Diphenyl_diselenide

    A reaction characteristic of Ph 2 Se 2 is its reduction: . Ph 2 Se 2 + 2 Na → 2 PhSeNa. PhSeNa is a useful nucleophile used to introduce the phenylselenyl group by nucleophilic substitution of alkyl halides, alkyl sulfonates (mesylates or tosylates) and epoxides.

  8. Selenic acid - Wikipedia

    en.wikipedia.org/wiki/Selenic_acid

    Like sulfuric acid, selenic acid is a strong acid that is hygroscopic and extremely soluble in water. Concentrated solutions are viscous. Crystalline mono- and di-hydrates are known. [6]

  9. Sodium hydroselenide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroselenide

    Sodium hydroselenide is an inorganic compound with the chemical formula Na Se H. It is a salt of hydrogen selenide. It consist of sodium cations Na + and hydroselenide anions − SeH. Each unit consists of one sodium, one selenium, and one hydrogen atom. Sodium hydroselenide is a selenium analog of sodium hydroxide NaOH.
