  2. Magnesium bromide - Wikipedia

    en.wikipedia.org/wiki/Magnesium_bromide

    Magnesium bromide can be synthesized by treating magnesium oxide (and related basic salts) with hydrobromic acid. [3] It can also be made by reacting magnesium carbonate and hydrobromic acids, and collecting the solid left after evaporation. [2] As suggested by its easy conversion to various hydrates, anhydrous MgBr 2 is a Lewis acid.

  3. Grignard reagent - Wikipedia

    en.wikipedia.org/wiki/Grignard_reagent

    Addition of preformed Grignard reagent is often used as the initiator. Specially activated magnesium, such as Rieke magnesium, circumvents this problem. [5] The oxide layer can also be broken up using ultrasound, using a stirring rod to scratch the oxidized layer off, [6] or by adding a few drops of iodine or 1,2-Diiodoethane.

    Organocopper complexes in particular react sluggishly in the absence of a Lewis acid. Although magnesium bromide generated in situ from the reaction of Grignard reagents and copper(I) halides can serve this role (see above), external Lewis acids are also useful. In the presence of boron trifluoride etherate, organocopper complexes are able to ...

  5. Bromide - Wikipedia

    en.wikipedia.org/wiki/Bromide

    Bromide salts are used in hot tubs as mild germicidal agents to generate in situ hypobromite. The bromide ion is antiepileptic and as bromide salt, is used in veterinary medicine in the US. The kidneys excrete bromide ions. The half-life of bromide in the human body (12 days) is long compared with many pharmaceuticals, making dosing challenging ...

    A solution of a carbonyl compound is added to a Grignard reagent. (See gallery) An example of a Grignard reaction (R 2 or R 3 could be hydrogen). The Grignard reaction (French:) is an organometallic chemical reaction in which, according to the classical definition, carbon alkyl, allyl, vinyl, or aryl magnesium halides (Grignard reagent) are added to the carbonyl groups of either an aldehyde or ...
