ethylmagnesium bromide reaction
Apart from acting as the synthetic equivalent of an ethyl anion synthon for nucleophilic addition, ethylmagnesium bromide may be used as a strong base to deprotonate various substrates such as alkynes:
- RC≡CH + EtMgBr → RC≡CMgBr + EtH
In this application, ethylmagnesium bromide has been supplanted by the wide availability of organolithium reagents.
ethylmagnesium bromide reacts with water
The Reaction of Ethyl Magnesium Bromide with water will give ethane .
Preparation of ethylmagnesium bromide
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
