2-(Ethoxycarbonyl)ethylzinc bromide - Introduction
3-Ethoxy-3-oxopropylzinc bromide solution(3-Ethoxy-3-oxopropylzinc bromide solution) is an organic zinc compound solution. Its chemical formula is C6H11BrO2Zn and its molecular weight is 253.34g/mol.
Nature:
-Appearance: 3-Ethoxy-3-oxopropylzinc bromide solution is usually a colorless to light yellow liquid.
-Stability: It is relatively stable under dry conditions. But it is easy to decompose in humidity or air.
-Solubility: It is soluble in inert solvents such as ether, disulfide and dichloromethane.
Use:
3-Ethoxy-3-oxopropylzinc bromide solution can be used as a reagent in organic synthesis, mainly used in the zincation reaction of halogenated hydrocarbons to prepare organic zinc reagents. These organic zinc reagents are often used in organic synthesis to synthesize organic compounds such as alcohols, ketones, aldehydes and olefins.
Preparation Method:
The method of preparing 3-Ethoxy-3-oxopropylzinc bromide solution is generally by reacting zinc bromide with 3-ethoxy-3-oxopropane in a suitable solvent, usually at low temperatures and under an inert atmosphere.
Safety Information:
3-Ethoxy-3-oxopropylzinc bromide solution is a chemical substance that has potential harm to human body and environment. It is necessary to take appropriate protective measures during use, such as wearing chemical protective gloves and goggles, to ensure that the operation is carried out in a well-ventilated laboratory environment. At the same time, avoid contact with the skin, eyes and respiratory tract, and try to avoid inhalation of its volatiles. When disposing of waste, it should be properly disposed of in accordance with local regulations.
