112981-69-8 - Introduction
3,5-Bis(trifluoromethyl)phenylmagnesium bromide is an organic compound. Its chemical formula is C8H4BrF6Mg and its molecular weight is 295.23.
This compound is an organic magnesium reagent, which belongs to a kind of Grignard reagent. It is often used as a complexing reagent and alkali reagent in organic synthesis. It is chemically very active and can react with many organic compounds, especially through addition reactions to form carbon-carbon bonds.
The method for preparing 3,5-Bis(trifluoromethyl)phenylmagnesium bromide is usually obtained by the reaction of Grignard reagent. The 3,5-bis (trifluoromethyl) phenyl bromide is first reacted with magnesium powder, typically in a solvent of diethyl ether or tetrahydrofuran. After completion of the reaction, the magnesium reagent may be neutralized with an acid or water.
In the use in the laboratory, it is necessary to pay attention to the safety of 3,5-Bis(trifluoromethyl)phenylmagnesium bromide. It is a combustible that can react with oxygen in the air to produce flammable hydrogen. In addition, it is also a corrosive agent and irritating to the skin and eyes. Therefore, you must wear appropriate protective equipment to avoid direct contact and inhalation of gas. At the same time, make sure to operate under safe ventilation.
