    en.wikipedia.org/wiki/Sodium_amide

    Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2.It is a salt composed of the sodium cation and the azanide anion.

  3. Chichibabin reaction - Wikipedia

    en.wikipedia.org/wiki/Chichibabin_reaction

    The Chichibabin reaction (pronounced ' (chē')-chē-bā-bēn) is a method for producing 2-aminopyridine derivatives by the reaction of pyridine with sodium amide.It was reported by Aleksei Chichibabin in 1914. [1]

  4. Sodium hydride - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydride

    Sodium hydride is the chemical compound with the empirical formula Na H.This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis.NaH is a saline (salt-like) hydride, composed of Na + and H − ions, in contrast to molecular hydrides such as borane, silane, germane, ammonia, and methane.

  5. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    The main use of sodium nitrite is for the industrial production of organonitrogen compounds. It is a reagent for conversion of amines into diazo compounds, which are key precursors to many dyes, such as diazo dyes.

  6. Azide - Wikipedia

    en.wikipedia.org/wiki/Azide

    In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]

  7. Amide - Wikipedia

    en.wikipedia.org/wiki/Amide

    The proton of a primary or secondary amide does not dissociate readily; its pK a is usually well above 15. Conversely, under extremely acidic conditions, the carbonyl oxygen can become protonated with a pK a of roughly −1. It is not only because of the positive charge on the nitrogen but also because of the negative charge on the oxygen ...

  8. Birch reduction - Wikipedia

    en.wikipedia.org/wiki/Birch_reduction

    The Birch reduction is an organic reaction that is used to convert arenes to 1,4-cyclohexadienes.The reaction is named after the Australian chemist Arthur Birch and involves the organic reduction of aromatic rings in an amine solvent (traditionally liquid ammonia) with an alkali metal (traditionally sodium) and a proton source (traditionally an alcohol).

  9. Triple bond - Wikipedia

    en.wikipedia.org/wiki/Triple_bond

    Structure and AFM image of dehydrobenzo[12]annulene, where benzene rings are held together by triple bonds. A triple bond in chemistry is a chemical bond between two atoms involving six bonding electrons instead of the usual two in a covalent single bond.
