Methylmagnesium Bromide Chemical Properties,Usage,Production

Chemical Properties

Clear brown solution when properly stored

Uses

Grignard reagent in greener solvent, 2-methyltetrahydrofuran (2-MeTHF)

Uses

Methylmagnesium bromide is widely used in organic synthesis.

Application

Methylmagnesium bromide solution (3M in diethyl ether) be used to synthesize:
3(4R)-{3(2R,3S)-[4′-(1′-triphenylmethyl)imidazole]-2-bromo-1-oxobutyl)-4-phenyl2-oxazolidinone.
Benzyl 2-(2-oxopropyl)piperidine-1-carboxylate.
(R*, R*) 1-[1-(1-phenylethyl)pyrrolidin-2-yl]propan-2-one).

Definition

Available in solution inether.

General Description

A colorless cloudy solution in diethyl ether. Flash point -49°F. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Reacts with water or moisture in the air to form flammable methane gas. The heat from this reaction may be sufficient to ignite the produced methane [AAR 1991]. Unstable peroxides may form with exposure of the ether to air. This is a slow process.

Reactivity Profile

Organometallics, such as METHYL MAGNESIUM BROMIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases.

Hazard

Flammable, dangerous fire and explosionrisk.

Health Hazard

Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Fire Hazard

Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.

reaction suitability

reaction type: Grignard Reaction

Safety Profile

May ignite spontaneously in air. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes.

Solubility in organics

Solubility: MeMgBr (Methylmagnesium Bromide) and MeMgI sol Et2O; MeMgCl and MeMgBr sol THF. MgI2 precipitates when MeMgI is prepared in THF, leaving mainly Me2Mg in the solution; some MgCl2 generally precipitates when MeMgCl is prepared in Et2O, particularly if the solution lasts several days. All are insoluble in hydrocarbons.
