  2. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    For example, consider radical bromination of toluene: [5] bromination of toluene with hydrobromic acid and hydrogen peroxide in water. This reaction takes place on water instead of an organic solvent and the bromine is obtained from oxidation of hydrobromic acid with hydrogen peroxide. An incandescent light bulb suffices to radicalize.

  3. Bromotoluene - Wikipedia

    en.wikipedia.org/wiki/Bromotoluene

    Bromotoluenes are aryl bromides based on toluene in which at least one aromatic hydrogen atom is replaced with a bromine atom. They have the general formula C 7 H 8–n Br n, where n = 1–5 is the number of bromine atoms.

  4. Halogen addition reaction - Wikipedia

    en.wikipedia.org/wiki/Halogen_addition_reaction

    In 1967 the group of George A. Olah obtained NMR spectra of tetramethylethylenebromonium ions by dissolving 2,3-dibromo-2,3-dimethylbutane in magic acid at −60 °C. [5] The spectrum for the corresponding fluorine compound on the other hand was consistent with a rapidly equilibrating pair of β-fluorocarbocations.

  5. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Bromination is more selective than chlorination because the reaction is less exothermic. Illustrative of the bromination of an alkene is the route to the anesthetic halothane from trichloroethylene: [6] Iodination and bromination can be effected by the addition of iodine and bromine to alkenes.

  6. Electrophilic halogenation - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_halogenation

    The mechanism for bromination of benzene. The mechanism for iodination is slightly different: iodine (I 2) is treated with an oxidizing agent such as nitric acid to obtain the electrophilic iodine ("I +", probably IONO 2). Other conditions for iodination include I 2, HIO 3, H 2 SO 4, and N-iodosuccinimide, H 2 SO 4.

    January 3, 2025 at 4:07 PM Study: Eating This Diet May Ease Chronic Pain Getty Images Nearly 21 percent of Americans live with chronic pain, an experience that can be life-altering for many.

  8. Benzyl bromide - Wikipedia

    en.wikipedia.org/wiki/Benzyl_bromide

    Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]

    There was a 3% reduction per serving a week of dark chocolate. The observed relationship was linear. Researchers found no significant association between milk chocolate intake and type 2 diabetes ...
