  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. Ammoxidation - Wikipedia

    en.wikipedia.org/wiki/Ammoxidation

    In organic chemistry, ammoxidation is a process for the production of nitriles (R−C≡N) using ammonia (NH 3) and oxygen (O 2). It is sometimes called the SOHIO process, acknowledging that ammoxidation was developed at Standard Oil of Ohio. [1] [2] The usual substrates are alkenes.

  4. Hofmann rearrangement - Wikipedia

    en.wikipedia.org/wiki/Hofmann_rearrangement

    The Hofmann rearrangement (Hofmann degradation) is the organic reaction of a primary amide to a primary amine with one less carbon atom. [1] [2] [3] The reaction involves oxidation of the nitrogen followed by rearrangement of the carbonyl and nitrogen to give an isocyanate intermediate.

  5. Electrophilic halogenation - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_halogenation

    The reaction mechanism for chlorination of benzene is the same as bromination of benzene. Iron(III) bromide and iron(III) chloride become inactivated if they react with water, including moisture in the air. Therefore, they are generated by adding iron filings to bromine or chlorine. Here is the mechanism of this reaction:

  6. Benzonitrile - Wikipedia

    en.wikipedia.org/wiki/Benzonitrile

    Benzonitrile is a useful solvent and a versatile precursor to many derivatives. It reacts with amines to afford N-substituted benzamides after hydrolysis. [3] It is a precursor to diphenylmethanimine via reaction with phenylmagnesium bromide followed by methanolysis.

  7. Bromine compounds - Wikipedia

    Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...

  8. Benzotrichloride - Wikipedia

    en.wikipedia.org/wiki/Benzotrichloride

    Benzotrichloride is a poorly water-soluble, clear to yellowish liquid with a penetrating odor. It hydrolyzes rapidly to benzoic acid and hydrochloric acid with a half life of about 2.4 minutes, thus making the compound unstable in the presence of water. [2]

  9. N-Bromosuccinimide - Wikipedia

    en.wikipedia.org/wiki/N-Bromosuccinimide

    In the above reaction, while a mixture of isomeric allylic bromide products are possible, only one is created due to the greater stability of the 4-position radical over the methyl-centered radical. Bromination of carbonyl derivatives
