  2. 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.

    en.wikipedia.org/wiki/Selenoxide_elimination

    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.

  4. 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 ...

    en.wikipedia.org/wiki/Category:Methyl_compounds

    Methyl compounds are chemical compounds formally derived from methane by replacement of one hydrogen atom with other atoms or functional groups. Methyl compounds contain the methyl group , CH 3 , and have the general formula CH 3 X, where X is any chemical element or group.

  6. Selenol - Wikipedia

    en.wikipedia.org/wiki/Selenol

    Methaneselenol (commonly named "methylselenol") (CH 3 SeH), which can be produced in vitro by incubating selenomethionine with a bacterial methionine gamma-lyase (METase) enzyme, by biological methylation of selenide ion or in vivo by reduction of methaneseleninic acid (CH 3 −Se(=O)−OH), has been invoked to explain the anticancer activity ...

  7. Benzeneselenol - Wikipedia

    en.wikipedia.org/wiki/Benzeneselenol

    More so than thiophenol, benzeneselenol is easily oxidized by air. The facility of this reaction reflects the weakness of the Se-H bond, bond dissociation energy of which is estimated to be between 67 and 74 kcal/mol. [1] In contrast, the S-H BDE for thiophenol is near 80 kcal/mol. [3] The product is diphenyl diselenide as shown in this idealized equation:

  8. Hydroselenide - Wikipedia

    en.wikipedia.org/wiki/Hydroselenide

    A hydroselenide (or biselenide or selanide) is an ion or chemical compound containing the [SeH] − ion. The radical HSe is a pseudohalogen.Hydroselenide can be a ligand in transition metal complexes where it can be attached to a single atom, or bridge two atoms.

  9. Methaneselenol - Wikipedia

    en.wikipedia.org/wiki/Methaneselenol

    Methaneselenol is the organoselenium compound with the formula C H 3 SeH.It is the simplest selenol.A colorless gas, it is notorious for its foul odor. It is prepared by reaction of methyl lithium or a methyl Grignard reagent with selenium followed by protonation of the product.
