Organomagnesium compounds

The interaction of alkyl halide with Mg metal in a suitable ether solvent is the common method for the synthesis of the Grignard reagent.

Hydrolysis Grignard Reactions and Reduction

Organomagnesium halides are Grignard reagents. Francois Auguste Victor Grignard, a French chemist who received the Nobel Prize in Chemistry in 1912, created these highly useful reagents.
