  2. Nef reaction - Wikipedia

    en.wikipedia.org/wiki/Nef_reaction

    The reaction has been the subject of several literature reviews. [1] [2] [3] The Nef reaction: 1. Salt of a nitroalkane 3. Ketone 4. Nitrous oxide. The reaction was reported in 1894 by the chemist John Ulric Nef, [4] who treated the sodium salt of nitroethane with sulfuric acid resulting in an 85–89% yield of nitrous oxide and at least 70% ...

  3. Nitroethane - Wikipedia

    en.wikipedia.org/wiki/Nitroethane

    Nitroethane is an organic compound having the chemical formula C 2 H 5 NO 2. Similar in many regards to nitromethane , nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor.

  4. Nitro compound - Wikipedia

    en.wikipedia.org/wiki/Nitro_compound

    In the so-called Ter Meer reaction (1876) named after Edmund ter Meer, [14] the reactant is a 1,1-halonitroalkane: The reaction mechanism is proposed in which in the first slow step a proton is abstracted from nitroalkane 1 to a carbanion 2 followed by protonation to an aci-nitro 3 and finally nucleophilic displacement of chlorine based on an ...

  5. Methyl nitrite - Wikipedia

    en.wikipedia.org/wiki/Methyl_nitrite

    Note that nitrogen is a better nucleophile than oxygen and most nitrites would react via an S N 2-like mechanism and the major product would be nitromethane. For example, sodium and potassium nitrite reacting with iodomethane would produce mostly nitromethane, with methyl nitrite as the minor product.

  6. Henry reaction - Wikipedia

    en.wikipedia.org/wiki/Henry_reaction

    The figure below illustrates one of the commonly accepted models for stereoselection without any modification to the Henry reaction. In this model, stereoselectivity is governed by the size of the R groups in the model (such as a carbon chain), as well as by a transition state that minimizes dipole by orienting the nitro group and carbonyl oxygen anti each other (on opposite sides of the ...

  7. 1-Nitropropane - Wikipedia

    en.wikipedia.org/wiki/1-Nitropropane

    1-nitropropane is produced industrially by the reaction of propane and nitric acid. This reaction forms four nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. 1-nitropropane is also a byproduct of the process for making 2-nitropropane, which is done by vapour phase nitration of propane.

  9. Phenyl-2-nitropropene - Wikipedia

    en.wikipedia.org/wiki/Phenyl-2-nitropropene

    In the lab, phenyl-2-nitropropene is produced by the reaction of benzaldehyde and nitroethane in the presence of a basic catalyst like n-butylamine.The reaction is a nitroaldol reaction, and is a variant of a Knoevenagel condensation reaction, which is one of a broader class of reactions called Henry condensations, or simply Henry reactions.
