  2. Imine - Wikipedia

    en.wikipedia.org/wiki/Imine

    The term "imine" was coined in 1883 by the German chemist Albert Ladenburg. [6] Usually imines refer to compounds with the general formula R 2 C=NR, as discussed below. [7] In the older literature, imine refers to the aza-analogue of an epoxide. Thus, ethylenimine is the three-membered ring species aziridine C 2 H 4 NH. [8]

  3. Schiff base - Wikipedia

    en.wikipedia.org/wiki/Schiff_base

    General structure of an imine. Schiff bases are imines in which R 3 is an alkyl or aryl group (not a hydrogen). R 1 and R 2 may be hydrogens General structure of an azomethine compound. In organic chemistry, a Schiff base (named after Hugo Schiff) is a compound with the general structure R 1 R 2 C=NR 3 (R 3 = alkyl or aryl, but not hydrogen).

  4. Oxime - Wikipedia

    en.wikipedia.org/wiki/Oxime

    In organic chemistry, an oxime is an organic compound belonging to the imines, with the general formula RR’C=N−OH, where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds.

  5. Ethanimine - Wikipedia

    en.wikipedia.org/wiki/Ethanimine

    Ethanimine is an organonitrogen compound classified as an imine. It is formed by reacting acetaldehyde and ammonia, but rapidly polymerizes to acetaldehyde ammonia trimer. It has two tautomers: ethanimine, an imine, and ethenamine or aminoethylene, an amine. Ethanimine has two hydrogens on the carbon, while ethenamine has two on the nitrogen atom.

  6. Acetone imine - Wikipedia

    en.wikipedia.org/wiki/Acetone_imine

    Acetone imine, or 2-propanimine is an organic compound and an imine with the chemical formula (CH 3) 2 CNH. It is a volatile and flammable liquid at room temperature. It is the simplest ketimine. This compound is mainly of academic interest.

  7. Reductive amination - Wikipedia

    en.wikipedia.org/wiki/Reductive_amination

    The intermediate imine can be isolated or reacted in-situ with a suitable reducing agent (e.g., sodium borohydride) to produce the amine product. [2] Intramolecular reductive amination can also occur to afford a cyclic amine product if the amine and carbonyl are on the same molecule of starting material.

  8. Semicarbazone - Wikipedia

    en.wikipedia.org/wiki/Semicarbazone

    In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide. They are classified as imine derivatives because they are formed from the reaction of an aldehyde or ketone with the terminal -NH 2 group of semicarbazide, which behaves very similarly to primary amines.

  9. Methylene imine - Wikipedia

    en.wikipedia.org/wiki/Methylene_imine

    Methylene imine is an organic compound with the chemical formula H 2 C=NH. The simplest imine, it is a stable, colorless gas that has been detected throughout the universe. [1] Structural parameters determined by microwave spectroscopy include a C=N bond length of 1.27 Å, an N–H bond length of 1.02 Å and an H−N=C bond angle of 110.5°. [2]
