(4-Biphenylyl)magnesium bromide - Introduction
4-Biphenylmagnesium bromide, also known as tetraphenylmagnesium bromide, has the chemical formula (C6H5) 4mgbr2. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
1. Appearance: 4-Biphenylmagnesium bromide is a white crystalline powder.
2. Solubility: Soluble in organic solvents such as ether, dimethylformamide and chlorinated hydrocarbons.
3. Stability: Stable at room temperature, but will decompose after being affected with moisture.
Use:
1. O-bromination reaction: 4-Biphenylmagnesium bromide is an organic synthetic reagent, which can be used for O-bromination reaction. This reaction is of great significance for the construction of bromine-containing organic compounds.
2. Metal Organic Chemistry: as a commonly used organic magnesium reagent, 4-Biphenylmagnesium bromide can be used to react to generate phenyl magnesium compounds. These magnesium compounds play an important role in the synthesis of complex organic molecules.
Preparation Method:
4-Biphenylmagnesium bromide is usually prepared by reacting benzene bromide with magnesium bromide.
Safety Information:
1. 4-Biphenylmagnesium bromide is irritating and should be avoided in contact with skin and eyes. Wear appropriate protective equipment, including gloves and goggles, when handling.
2. Please store it in a dry and sealed container, away from fire and high temperature environment.
3. Avoid inhaling its dust or contacting its solution during use. If inhaled or ingested, please consult a doctor.
4. Should be operated in a well-ventilated place to avoid the accumulation of steam.
5. Avoid contact with oxidants and combustibles.
Please note that the above description is for reference only. Please follow the chemical safety procedures and refer to the specific product instructions when using it.
