When the Grignard reagent is in excess, an additional second-order reaction takes place between the complex EtMgBr·E·D and the monosolvated Grignard reagent. The rate constants are related to the basicities of the different ethers, E, used. The results confirm that the reaction proceeds via ...

格氏反应(Grignard Reaction) Grignard Reaction Halogenated hydrocarbons in anhydrous ether or tetrahydrofuran and generate alkyl magnesium metal magnesium halide RMgX, the organic magnesium compounds called Grignard reagent (Grignard Reagent). Grignard reagent can react with aldehydes, ketones and other ...
Grignard Synthesis The Grignard reagent is synthesized by reacting to an organic halide with magnesium in a diethyl ether orTHFsolution. The R group on the organic halide will determine the R group on the Grignard reagent. The Grignard synthesis replaces the halogen on the organic halide with th...

Nor is there anything wrong with using magnesium metal to form a Grignard reagent. The only place where a mistake could have been made is in the choice of the solvent. The solvent that was used was ethanol (CH3CH2OH), whereas the usual solvent for a Grignard reagent is diethyl ether. ...
