  2. Triethylamine - Wikipedia

    en.wikipedia.org/wiki/Triethylamine

    Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. Like triethanolamine and tetraethylammonium, it is often abbreviated TEA. [8] [9] It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia.

  3. Tetraethylammonium - Wikipedia

    en.wikipedia.org/wiki/Tetraethylammonium

    Tetraethylammonium (TEA) is a quaternary ammonium cation with the chemical formula [Et 4 N] +, consisting of four ethyl groups (−C 2 H 5, denoted Et) attached to a central nitrogen atom. It is a counterion used in the research laboratory to prepare lipophilic salts of inorganic anions.

  4. Swern oxidation - Wikipedia

    en.wikipedia.org/wiki/Swern_oxidation

    In organic chemistry, the Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol (−OH) is oxidized to an aldehyde (−CH=O) or ketone (>C=O) using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.

  5. Triethanolamine - Wikipedia

    en.wikipedia.org/wiki/Triethanolamine

    Triethanolamine, or TEOA, is an organic compound with the chemical formula N(CH 2 CH 2 OH) 3. It is a colourless, viscous liquid. It is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. [3] It is a colourless compound although samples may appear yellow because ...

  6. Non-nucleophilic base - Wikipedia

    en.wikipedia.org/wiki/Non-nucleophilic_base

    As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile.Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.

  7. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. [1]

  8. Electron-withdrawing group - Wikipedia

    en.wikipedia.org/wiki/Electron-withdrawing_group

    The strength of the electron-withdrawing group is inversely proportional to the pKa of the carboxylic acid. [2] The inductive effect is cumulative: trichloroacetic acid is 1000x stronger than chloroacetic acid. The impact of the EWG on pKa decreases with distances from the carboxylic group.

  9. Solvent effects - Wikipedia

    In the table above, it can be seen that water is the most polar-solvent, followed by DMSO, and then acetonitrile. Consider the following acid dissociation equilibrium: HA ⇌ A − + H + Water, being the most polar-solvent listed above, stabilizes the ionized species to a greater extent than does DMSO or Acetonitrile.
