Magnesium compounds chemistry

The alkylltlhium compounds are usually colorless, soluble in organic solvents, and capable of distillation or sublimation. They are nonelec -trolyies and are widely used in synthetic organic chemistry, since, like other lithium compounds, they resemble in their properties the corresponding magnesium compounds. 

Of the organometallic compounds of Group II elements, undoubtedly the chemistry of the magnesium compounds is best known. By contrast, the remaining elements in this group have received less attention and it is only recently that more information on organo derivatives of beryllium and, to lesser extent, of calcium, strontium, and barium has become available. Therefore, most of the observations regarding redistribution equilibria have been of more or less qualitative nature. 

Trialkylaluminum and alkylaluminum hydrides associate with alkyl or hydride bridges. Since there are no available lone-pair electrons with which to form bridges by standard two-center two-electron interactions, multicenter bonding is invoked in the same manner as for electron-deficient boranes (see Boron Hydrides), alkyllithium (see Alkali Metals Organometallic Chemistry), dialkylberyllium and dialkylmagnesium compounds (see Beryllium Magnesium Organometallic Chemistry).

The chemistry of these metals is largely dominated by the magnesium compounds, the Grignard reagents being of primary importance in organic synthesis. 

The synthesis of new perfluoroaliphatic compounds of magnesium and lithium has continued, although at a reduced effort Perfluoroorganometallics offer a variety of reactions with numerous substrates, which contributed to the development of the chemistry of fluorine containing compounds...
