ETHYLMAGNESIUM BROMIDE(Cas 925-90-6) Usage
Chemical Properties |
Ethylmagnesium bromide is generally sold as a dark brown solution and can be dissolved in diethyl ether, butyl ether, isopropyl ether, THF and anisole. |
Uses |
Ethylmagnesium Bromide is a useful reagent in preparation of zirconium complexes having two phenoxy-imine chelate ligands for olefin polymerization. |
Preparation |
Ethylmagnesium bromide is commercially available, usually as a solution in diethyl ether or tetrahydrofuran. It may be prepared in the normal manner of Grignard reagents — by reacting bromoethane with magnesium in diethyl ether: EtBr + Mg → EtMgBr |
Reactions |
Ethylmagnesium bromide reacts with water to produce ethane.CH3CH2MgBr+H2O→CH3-CH3+Mg(OH)BrReaction of ethylmagnesium bromide with ethyl acetate in the presence of styrene and titanium(IV) isopropoxide as a catalyst leads to (Z)-1-methyl-2-phenylcyclopropanol in 42% yield. |
General Description |
Ethylmagnesium bromide, an organomagnesium compound, is commonly known as Grignard reagent. It is a powerful carbon nucleophile mainly used for C-C bond formation. Ethylmagnesium bromide solution (3.0 M in diethyl ether) can be used for copper(I)-catalyzed allylic substitution reaction.Grignard reagents are organometallic compounds discovered by a French chemist, Victor Grignard in 1900. These compounds can be obtained as a formula “RMgX” by the reaction of halogenated hydrocarbons with magnesium metal in anhydrous solvents such as diethyl ether,1) and have been widely used in organic synthesis. |
Hazard |
Flammable, dangerous fire risk. |
