  2. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    However, such compounds may still be referred to as aliphatic if the hydrocarbon portion of the molecule is aliphatic, e.g. aliphatic amines, to differentiate them from aromatic amines. The least complex aliphatic compound is methane (CH 4).

  3. 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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...

  4. Aromatic amine - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amine

    In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH 2. Such compounds occur widely. [1]

  5. Proline - Wikipedia

    en.wikipedia.org/wiki/Proline

    2 but is rather a secondary amine. The secondary amine nitrogen is in the protonated form (NH 2 +) under biological conditions, while the carboxyl group is in the deprotonated −COO − form. The "side chain" from the α carbon connects to the nitrogen forming a pyrrolidine loop, classifying it as a aliphatic amino acid.

  6. Aniline - Wikipedia

    en.wikipedia.org/wiki/Aniline

    Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.

  7. Schiff base - Wikipedia

    en.wikipedia.org/wiki/Schiff_base

    Schiff bases can be synthesized from an aliphatic or aromatic amine and a carbonyl compound by nucleophilic addition forming a hemiaminal, followed by a dehydration to generate an imine. In a typical reaction, 4,4'-oxydianiline reacts with o-vanillin: [5]

  8. Amide - Wikipedia

    en.wikipedia.org/wiki/Amide

    Compared to amines, amides are very weak bases. While the conjugate acid of an amine has a pK a of about 9.5, the conjugate acid of an amide has a pK a around −0.5. Therefore, compared to amines, amides do not have acid–base properties that are as noticeable in water. This relative lack of basicity is explained by the withdrawing of ...

  9. Amine oxide - Wikipedia

    en.wikipedia.org/wiki/Amine_oxide

    Almost all amine oxides are prepared by the oxidation of either tertiary aliphatic amines or aromatic N-heterocycles. Hydrogen peroxide is the most common reagent both industrially and in academia, however peracids are also important. [6] More specialised oxidising agents can see niche use, for instance Caro's acid or mCPBA. Spontaneous or ...
