  2. Gabriel synthesis - Wikipedia

    en.wikipedia.org/wiki/Gabriel_synthesis

    The Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines.Traditionally, the reaction uses potassium phthalimide. [1] [2] [3] The reaction is named after the German chemist Siegmund Gabriel.

  3. Hinsberg reaction - Wikipedia

    en.wikipedia.org/wiki/Hinsberg_reaction

    The Hinsberg reaction is a chemical test for the detection of primary, secondary and tertiary amines.The reaction was first described by Oscar Hinsberg in 1890. [1] [2] In this test, the amine is shaken well with the Hinsberg reagent (benzenesulfonyl chloride) in the presence of aqueous alkali (either KOH or NaOH).

  4. Hydroxylamine-O-sulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Hydroxylamine-O-sulfonic_acid

    Under basic conditions in the presence of primary amines, hydroxylamine-O-sulfonic acid forms with aldehydes and ketones (e.g. cyclohexanone [22]) diaziridines, which can easily be oxidized to the more stable diazirines. 3,3-Pentamethylendiaziridin durch Reaktion of Cyclohexanon mit HOSA

  5. Amine - Wikipedia

    en.wikipedia.org/wiki/Amine

    Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...

  6. Ammonolysis - Wikipedia

    en.wikipedia.org/wiki/Ammonolysis

    In chemistry, ammonolysis (/am·mo·nol·y·sis/) is the process of splitting ammonia into + +. [1] Ammonolysis reactions can be conducted with organic compounds to produce amines (molecules containing a nitrogen atom with a lone pair, :N), [2] or with inorganic compounds to produce nitrides.

  7. Pyramidal inversion - Wikipedia

    en.wikipedia.org/wiki/Pyramidal_inversion

    In chemistry, pyramidal inversion (also umbrella inversion) is a fluxional process in compounds with a pyramidal molecule, such as ammonia (NH 3) "turns inside out". [1] [2] It is a rapid oscillation of the atom and substituents, the molecule or ion passing through a planar transition state. [3]

  8. Sulfinylamine - Wikipedia

    en.wikipedia.org/wiki/Sulfinylamine

    General structure of an N-sulfinyl amine N-Sulfinylaniline is a common sulfinylamine. Sulfinylamines (formerly N-sulfinyl amines) are organosulfur compounds with the formula RNSO where R = an organic substituent. These compounds are, formally speaking, derivatives of HN=S=O, i.e. analogues of sulfur dioxide and of sulfur diimide.

  9. Leuckart reaction - Wikipedia

    en.wikipedia.org/wiki/Leuckart_reaction

    The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines. The reaction is an example of reductive amination. [1] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. It requires high temperatures, usually between 120 and 130 °C; for the ...
