[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)Br
