2-PROPYLZINC BROMIDE SOLUTION 0.5M IN T& - Introduction
2-Propylzinc bromide is an organic compound with the chemical formula C3H7ZnBr. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 2-Propylzine bromide is a colorless to yellow liquid.
-Solubility: It is soluble in non-polar solvents, such as ether, dimethylformamide and disulfide.
-Stability: It is easily decomposed by moisture in the air, and may cause spontaneous combustion.
Use:
-2-Propylzine bromide can be used as an important reagent in organic synthesis, commonly used for the alkylation of halogenated raw materials.
-It can be used to prepare other organic zinc reagents, such as 2-butyl zinc compounds.
Preparation Method:
2-Propylzinc bromide can be prepared by reacting propylmagnesium bromide with zinc chloride. The specific steps are as follows:
1. Under anhydrous conditions, the propyl magnesium bromide is stirred with zinc chloride dissolved in disulfide.
2. The reaction mixture was filtered to give the 2-Propylzinc bromide product.
Safety Information:
- 2-Propylzinc bromide is irritating and corrosive and may cause damage to the eyes, skin and respiratory system when in contact.
-Wear protective equipment, including chemical protective gloves, goggles, and respiratory protection.
-When in contact with moisture in the air, toxic gases may be produced.
-Do not contact with strong oxidants and strong acids.
-Store away from fire and heat sources and in a cool, dry and well-ventilated place.
Please note that the handling of such chemicals should be carried out in a suitable laboratory environment and follow relevant safe operating procedures.
