Grignardreagendid
Grignard reagents are organomagnesium compounds with the general formula R-Mg-X, where R is an organic group and X is a halogen. Discovered by Victor Grignard in 1900, these reagents are highly reactive and widely used in organic synthesis. They are typically prepared by reacting an organic halide with magnesium metal in an anhydrous ether solvent, such as diethyl ether or tetrahydrofuran. The reaction is sensitive to moisture and oxygen, requiring strict anhydrous conditions.
The carbon atom attached to the magnesium atom in a Grignard reagent carries a partial negative charge,
