  2. Imide - Wikipedia

    en.wikipedia.org/wiki/Imide

    A general linear imide functional group. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.

  3. Imine - Wikipedia

    en.wikipedia.org/wiki/Imine

    The relationship of imines to amines having double and single bonds can be correlated with imides and amides, as in succinimide vs acetamide. Imines are related to ketones and aldehydes by replacement of the oxygen with an NR group. When R = H, the compound is a primary imine, when R is hydrocarbyl, the compound is a

  4. Inorganic imide - Wikipedia

    en.wikipedia.org/wiki/Inorganic_imide

    The inorganic imide is an inorganic chemical compound containing an anion with the chemical formula HN 2− , in which nitrogen atom is covalently bonded to one hydrogen atom (as in lithium imide Li 2 NH and calcium imide CaNH ).

  5. 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).

  6. Polyethylenimine - Wikipedia

    en.wikipedia.org/wiki/Polyethylenimine

    Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.

  7. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions.The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.

  8. 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.

  9. Tautomer - Wikipedia

    en.wikipedia.org/wiki/Tautomer

    enamine – imine: H−N−C=C ⇌ N=C−C−H. cyanamide – carbodiimide; guanidine – guanidine – guanidine: With a central carbon surrounded by three nitrogens, a guanidine group allows this transform in three possible orientations
