103068-18-4 - Introduction
3-Diphenylmagnesium bromide is an organic compound with the chemical formula BrMg(C6H5)2, often abbreviated as Ph2MgBr. It is a white amorphous solid, often used as a reagent in organic synthesis.
3-diphenyl magnesium bromide can be used as Grignard reagent in organic synthesis. It can react with alkyl halides or alcohols to generate the corresponding alkyl magnesium bromide or magnesium alcohol bromide. These organic magnesium reagents have extremely high activity and can be used to synthesize organic compounds, such as alcohols, ethers, ketones and aldehydes.
the method of preparing 3-diphenyl magnesium bromide is generally to react bromobenzene with magnesium powder to generate Ph2MgBr. The reaction conditions need to be carried out under an inert gas (such as nitrogen) and under dry conditions to avoid the interference of moisture and oxygen on the reaction.
3-two phenyl magnesium bromide in the use of need to pay attention to safety matters. It is irritating and corrosive, avoid direct contact with skin and eyes. Appropriate protective gloves, glasses and laboratory coats should be worn during operation. In addition, due to the high activity of the organic magnesium reagent, the reaction process needs to be carried out under an inert atmosphere and under dry conditions to ensure the smooth progress of the reaction and safety.
