4-Cyanobenzylzinc bromide solution 0.5 in THF - Introduction
4-Cyanobenzylzinc bromide is an organic zinc reagent with the chemical formula of C8H6BrN2Zn. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 4-Cyanobenzylzinc bromide is usually a white or slightly yellow solid powder.
-Solubility: It is soluble in organic solvents (such as ether, dimethylformamide and acetone).
-Stability: 4-Cyanobenzylzinc bromide is relatively stable in the air, but a humid environment should be avoided.
Use:
-Organic synthesis reagent: 4-Cyanobenzylzinc bromide can be used as a reagent in organic synthesis reactions, and is often used to construct carbon-carbon bonds and carbon-cyanide bonds.
-Palladium-catalyzed cross-coupling reactions: It can also be used as a reagent in palladium-catalyzed cross-coupling reactions (such as Suzuki reaction and Stille reaction).
Preparation Method:
- 4-Cyanobenzylzinc bromide can be prepared by adding 4-cyanobenzyl bromide to a mixture of zinc oxide and dimethyl zinc bromide.
Safety Information:
- 4-Cyanobenzylzinc bromide is an organometallic reagent. Safety precautions to be paid attention to when using include:
-Avoid contact with skin and eyes, such as contact immediately with plenty of water rinse.
-The operation should be carried out in a well-ventilated laboratory to avoid inhaling its dust or vapor.
-Avoid contact with combustibles to prevent fire or explosion.
-storage should be sealed, away from heat and fire sources, away from humid environment.
-When using and handling the reagent should follow the relevant safety procedures.
