마그네슘, 브로모에틸- C화학적 특성, 용도, 생산
화학적 성질
Ethylmagnesium bromide is generally sold as a dark brown solution and can be dissolved in diethyl ether, butyl ether, isopropyl ether, THF and anisole.화학 반응
Ethylmagnesium bromide reacts with water to produce ethane.CH3CH2MgBr+H2O→CH3-CH3+Mg(OH)Br
Reaction 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.
일반 설명
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.
