Can Grignard Reagents React with Alkyl Halides?

Grignard reagents are Alkyl or aryl magnesium halides. A grignard reagent is prepared by treating dry alkyl or aryl halide with dry pure magnesium in dry ether. RMgX is grignard reagent. It can't react with alkyl halide to form magnesium halide.

What happens when Grignard reagent reacts with alkyl halide?

The organomagnesium compounds formed by the reaction of an alkyl or aryl halide with magnesium are called Grignard reagents. ... The halogen is converted to a halide anion, and the carbon bonds to the metal which has characteristics similar to a carbanion (R:-).

Why can't Grignard reagents react with alkyl halides?

The highly basic character of a Grignard reagent often results in an elimination reaction or no reaction at all. The transition state to substitute the alkyl halide is less stable than the Magnesium/Bromide(Halide) complex. This is due to a ligation formation between the solvent and the Magnesium atom.
