メチルマグネシウムブロミド (12%テトラヒドロフラン溶液, 約1mol/L)

化学的特性

Clear brown solution when properly stored

使用

Methylmagnesium bromide is widely used in organic synthesis.

主な応用

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).

定義

Available in solution inether.

一般的な説明

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

空気と水の反応

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.

反応プロフィール

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.

危険性

Flammable, dangerous fire and explosionrisk.

健康ハザード

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.

火災危険

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.

安全性プロファイル

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.
