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.
Magnesium chloride is an ionic compound, which can be electrolysed in a molten state to form magnesium and chlorine gas. The properties of magnesium bromide and magnesium iodide are similar. [citation needed] HMgX (X=Cl,Br,I) can be obtained by reacting the corresponding magnesium halide with magnesium hydride. [3]
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. Another option is to use sublimed magnesium or magnesium anthracene. [7]
Phenylmagnesium bromide, with the simplified formula C 6 H 5 MgBr, is a magnesium-containing organometallic compound. It is commercially available as a solution in diethyl ether or tetrahydrofuran (THF). Phenylmagnesium bromide is a Grignard reagent. It is often used as a synthetic equivalent for the phenyl "Ph −" synthon.
Cyclopentadienyl magnesium bromide is a chemical compound with the molecular formula C 5 H 5 MgBr. The molecule consists of a magnesium atom bonded to a bromine atom and a cyclopentadienyl group , a ring of five carbons each with one hydrogen atom.

n-Propylmagnesium bromide, often referred to as simply propylmagnesium bromide, is an organomagnesium compound with the chemical formula C 3 H 6 MgBr. As the Grignard reagent derived from 1-bromopropane , it is used for the n -propylation of electrophiles in organic synthesis.
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 add to sterically congested enones in moderate yield (effecting the same transformation ...
