  2. Work-up - Wikipedia

    en.wikipedia.org/wiki/Work-up

    The product is isolated from the mixture by the following work-up: [3] Synthesis of 4-methylcyclohexene with work-up step in red. A concentrated solution of sodium chloride in water, known as a brine solution, is added to the mixture and the layers are allowed to separate. The brine is used to remove any acid or water from the organic layer.

  3. Acid–base extraction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_extraction

    Acid–base extraction is a subclass of liquid–liquid extractions and involves the separation of chemical species from other acidic or basic compounds. [1] It is typically performed during the work-up step following a chemical synthesis to purify crude compounds [2] and results in the product being largely free of acidic or basic impurities.

  4. Hoesch reaction - Wikipedia

    en.wikipedia.org/wiki/Hoesch_reaction

    The mechanism of the reaction involves two steps. The first step is a nucleophilic addition to the nitrile with the aid of a polarizing Lewis acid, forming an imine, which is later hydrolyzed during the aqueous workup to yield the final aryl ketone. Hoesch reaction mechanism

  5. Chemical synthesis - Wikipedia

    en.wikipedia.org/wiki/Chemical_synthesis

    Chemical synthesis (chemical combination) is the artificial execution of chemical reactions to obtain one or several products. [1] This occurs by physical and chemical manipulations usually involving one or more reactions.

  6. 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone - Wikipedia

    en.wikipedia.org/wiki/2,3-Dichloro-5,6-dicyano-1...

    The resulting hydroquinone is poorly soluble in typical reaction solvents (dioxane, benzene, alkanes), which facilitates workup. Solutions of DDQ in benzene are red, due to the formation of a charge-transfer complex. [9]

  7. McMurry reaction - Wikipedia

    en.wikipedia.org/wiki/McMurry_reaction

    The McMurry reaction of benzophenone. The McMurry reaction is an organic reaction in which two ketone or aldehyde groups are coupled to form an alkene using a titanium chloride compound such as titanium(III) chloride and a reducing agent.

  9. Friedel–Crafts reaction - Wikipedia

    en.wikipedia.org/wiki/Friedel–Crafts_reaction

    Formyl chloride, for example, is too unstable to be isolated. Thus, synthesis of benzaldehyde through the Friedel–Crafts pathway requires that formyl chloride be synthesized in situ . This is accomplished by the Gattermann-Koch reaction , accomplished by treating benzene with carbon monoxide and hydrogen chloride under high pressure ...
