  2. 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

    en.wikipedia.org/wiki/Work-up

    In this example the organic layer is the product, which is a liquid at room temperature. The bottom aqueous layer is removed with a pipette and discarded. The top layer is transferred to an Erlenmeyer flask where it is treated with anhydrous sodium sulfate to remove any remaining water.

  4. Alpha hydroxycarboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Alpha_hydroxycarboxylic_acid

    For instance, the production of glycolic acid typically follows this method, utilizing a base-induced reaction, followed by acid workup. Similarly, unsaturated acids and fumarate and maleate esters undergo hydration to yield malic acid derivatives from esters, and 3-hydroxypropionic acid from acrylic acid .

  5. 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.

    en.wikipedia.org/wiki/Corey–House_synthesis

    The Corey–House synthesis (also called the Corey–Posner–Whitesides–House reaction and other permutations) is an organic reaction that involves the reaction of a lithium diorganylcuprate with an organic halide or pseudohalide (′) to form a new alkane, as well as an ill-defined organocopper species and lithium (pseudo)halide as byproducts.
