卤代物在无水乙醚或四氢呋喃中和金属镁作用生成烷基卤化镁RMgX,这种有机镁化合物被称作格氏试剂(Grignard Reagent)。格氏试剂作为亲核试剂可以与醛、酮、羧酸等化合物发生加成反应,这类反应被称作格氏反应(Grignard Reaction)。格氏试剂一经发现,此反应就成为非常重要的C-C键形成的方法。 反应特点: 一、格氏试剂主要...
The meaning of GRIGNARD REAGENT is any of various compounds of magnesium with an organic radical and a halogen (as ethyl-magnesium iodide C2H5MgI) that react readily (as with water, alcohols, amines, acids) in the Grignard reaction.
The invention relates to a Grignard reagent synthesis solvent used in the production of maltol. The solvent is characterized in that the solvent is mixed by the raw material with the mixture ratio of: 2.6-3.2 of cyclohexane, 0.8-1.2 of tetrahydrofuran. The invention has the advantages that: ...
The meaning of GRIGNARD REACTION is the reaction of a Grignard reagent with any of several types of compounds (as an aldehyde, ketone, or ester) to yield any of a variety of compounds (as an alcohol).

separate additions of different polyhaloaromatic compounds, such that the conversion of hydrocarbyl Grignard reagent to the desired perfluoroaryl Grignard reagent is essentially complete, and thus the reaction product is free or essentially free of agents that may negatively affect subsequent reactions. ...
(100 mL) were added to the reaction solution in order to quench the non-reacted organomagnesium reagent. The organic components were extracted by chloroform (300 mL), and the chloroform solution was washed several times with 0.5 mol/L NaHCO3 aq. (100 mL) and water. The solution was ...
Control of addition: reduction ratio in the Grignard reaction with ketones by a salt effect The yield of addition of a Grignard reagent to a hindered ketone has been enhanced at the expense of reduction by complexing the Grignard reagent with lithium perchlorate or tetrabutylammonium bromide.
