  2. Nitrile - Wikipedia

    en.wikipedia.org/wiki/Nitrile

    The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

  3. 1,3-Dipolar cycloaddition - Wikipedia

    en.wikipedia.org/wiki/1,3-Dipolar_cycloaddition

    1,3-dipolar cycloaddition with nitrile oxides is a widely used masked-aldol reaction. Cycloaddition between a nitrile oxide and an alkene yields the cyclic isoxazoline product, whereas the reaction with an alkyne yields the isoxazole.

    One other possible oxide that has not yet been synthesised is oxatetrazole (N 4 O), an aromatic ring. [15] Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts.

  5. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen . Nitric oxide is a free radical : it has an unpaired electron , which is sometimes denoted by a dot in its chemical formula ( • N=O or • NO).

    Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds: Charge-neutral

  7. 1,3-dipole - Wikipedia

    en.wikipedia.org/wiki/1,3-dipole

    In organic chemistry, a 1,3-dipolar compound or 1,3-dipole is a dipolar compound with delocalized electrons and a separation of charge over three atoms.They are reactants in 1,3-dipolar cycloadditions.

  8. Isoxazoline - Wikipedia

    en.wikipedia.org/wiki/Isoxazoline

    2-Isoxazolines are generally produced by the 1,3-dipolar cycloaddition of nitrile oxides with alkenes. [5] This has been applied in a diastereoselective manner in the synthesis of epothilones. [6] 3-isoxazolines are prepared from 2-isoxazolines via their N-methylation to form 2-isoxazolinium salts, followed by nucleophilic attack and ...

  9. Nitroso - Wikipedia

    en.wikipedia.org/wiki/Nitroso

    Structural formula of nitroso group. In organic chemistry, nitroso refers to a functional group in which the nitric oxide (−N=O) group is attached to an organic moiety.As such, various nitroso groups can be categorized as C-nitroso compounds (e.g., nitrosoalkanes; R−N=O), S-nitroso compounds (nitrosothiols; RS−N=O), N-nitroso compounds (e.g., nitrosamines, RN(−R’)−N=O), and O ...
