3,4-difluorobenzylzinc bromide solution - Introduction
bromo-[(3,4-difluorophenyl)methyl] Inc is an organic compound. Its molecular formula is C8H5BrF2Zn, and its relative molecular mass is 286.3g/mol.
Nature:
bromo-[(3,4-difluorophenyl)methyl]zinc is a colorless to light yellow solid. It is readily soluble in inert organic solvents (such as dimethylformamide, chlorinated methane, etc.), but insoluble in water. It is more sensitive to air and moisture, easy to decompose in the air.
Use:
bromo-[(3,4-difluorophenyl)methyl]zinc is an important reagent in organic synthesis. It is commonly used as a metal organic reagent to catalyze coupling reactions. It can be reacted with an organic halide to form the corresponding Allyl, propargyl or alkyl compound. Common reactions include Suzuki reaction, Stille reaction, etc. It is widely used in the fields of medicine, pesticide and material science.
Method:
The preparation of bromo-[(3,4-difluorophenyl)methyl]zinc is generally obtained by the reaction of zinc bromide and 3,4-difluorobenzyl Cadmium bromide. First, zinc bromide is reacted with Cadmium bromide in an inert solvent to form a mixture of zinc bromide and Cadmium bromide, and then the product is reacted with 3,4-difluorobenzyl bromide, bromo-[(3,4-difluorophenyl)methyl]zinc was obtained.
Safety Information:
bromo-[(3,4-difluorophenyl)methyl]zinc needs to be operated in a well-ventilated environment, avoiding contact with skin, eyes and inhalation. Appropriate protective equipment, such as protective gloves, safety glasses and face shields, should be worn. During use and storage, safety operating procedures should be strictly followed and contact with oxidants should be avoided to prevent fire or explosion. In case of accidental spills or poisoning, appropriate emergency treatment should be carried out in a timely manner and medical assistance should be sought.
