    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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...

  3. Balz–Schiemann reaction - Wikipedia

    en.wikipedia.org/wiki/Balz–Schiemann_reaction

    The Balz–Schiemann reaction (also called the Schiemann reaction) is a chemical reaction in which a primary aromatic amine is transformed to an aryl fluoride via a diazonium tetrafluoroborate intermediate. [1] [2] [3] This reaction is a traditional route to fluorobenzene and some related derivatives, [4] including 4-fluorobenzoic acid. [5]

  4. Schotten–Baumann reaction - Wikipedia

    en.wikipedia.org/wiki/Schotten–Baumann_reaction

    The Schotten–Baumann reaction is a method to synthesize amides from amines and acid chlorides: An example of a Schotten-Baumann reaction. Benzylamine reacts with acetyl chloride under Schotten-Baumann conditions to form N-benzylacetamide. Schotten–Baumann reaction also refers to the conversion of acid chloride to esters.

  5. 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]

  6. Schmidt reaction - Wikipedia

    en.wikipedia.org/wiki/Schmidt_reaction

    In organic chemistry, the Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually an aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen.

  7. Strecker amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Strecker_amino_acid_synthesis

    Using primary and secondary amines in place of ammonium was shown to yield N-substituted amino acids. [10] The classical Strecker synthesis gives racemic mixtures of α-amino acids as products, but several alternative procedures using asymmetric auxiliaries [11] or asymmetric catalysts [12] [13] have been developed.

  9. Amination - Wikipedia

    en.wikipedia.org/wiki/Amination

    Many alkyl amines are produced industrially by the amination of alcohols using ammonia in the presence of solid acid catalysts. Illustrative is the production of tert-butylamine: NH 3 + CH 2 =C(CH 3) 2 → H 2 NC(CH 3) 3. The Ritter reaction of isobutene with hydrogen cyanide is not useful in this case because it produces too much waste. [1]
