- Effective activation can also be achieved by stirring magnesium particles without solvent under an inert atmosphere. Photomicrographic observation of magnesium surfaces during Grignard reactions with and without activation has shown that the reaction proceeds at discrete initiation sites on the magnesium surfaces. Addition of iodine increases the density of reactive sites on the magnesium surfaces, while sonication does not appear to affect the magnesium surfaces directly. Highly reactive forms of magnesium can be used to achieve Grignard reaction of substrates, which are inert under the conditions described above, or which tend to give rise to side reactions, in particular Wurtz coupling.
- A slurry of finely powdered magnesium can be obtained by condensation of magnesium vapor into diethyl ether or THF. Highly reactive magnesium, known as Rieke magnesium, can be obtained by reduction of magnesium chloride with potassium in THF. Rieke magnesium is sufficiently reactive to induce Grignard reaction of alkyl fluorides, and for the preparation of unstable alkylmagnesium halides at low temperatures.
Magnesium reacts with anthracene in THF to form Mg(anthracene) (THF)3 complex 2.
Complex 2 decomposes in solvents other than THF to give an activated form of magnesium, which can be used to metallate allylic, benzylic, and propargylic halides. Polymer- and silica-supported derivatives of complex 2 have been reported to effect benzylic metallation in THF.
