4-氯-2-甲苯基溴化镁 0.5M 2-甲基四氢呋喃 - Introduction
bromide is an organic compound with the chemical formula C7H6BrClMg.
Nature:
The bromide is a solid, white crystal at room temperature. It has good solubility and is easily soluble in non-polar solvents such as ethers and cycloalkanes in anhydrous environments. It is stable in air, but reacts in water to produce hydrogen bromide gas.
Use:
bromide is one of the important reagents in organic synthesis. It can react with various organic halides to generate the corresponding reduced compounds. It is widely used in the construction of carbon-carbon bonds and the construction of organic molecules with specific structures. Commonly used in drug synthesis and pesticide synthesis and other fields.
Preparation Method:
The phosphonium bromide is generally prepared by the hard alkali method. First, an organic halide (e. g., 4-chloro-2-tolyl bromide) is reacted with magnesium powder to form an organic magnesium halide (e. g., 4-chloro-2-tolyl magnesium bromide). The preparation needs to be carried out under anhydrous conditions.
Safety Information:
g bromide irritant to skin, eyes and respiratory tract. Appropriate protective measures, such as gloves, goggles and protective masks, should be worn during operation. In the storage to be isolated from moisture and acids, keep the container closed. Avoid contact with open flame and high temperature material, can cause fire.
