1-Methyl-2-propenylmagnesium chloride - Introduction
chloride is an organic compound with the chemical formula C4H7ClMg. It is a colorless or light yellow liquid that will decompose at room temperature and emit a pungent odor. It has a density of 0.920g/cm3 and a melting point of -85°C.
chloride is mainly used as a reagent in organic synthesis, especially as a Grignard reagent. Grignard reagent is one of the important reagents commonly used in organic synthesis, which can react with a variety of compounds to generate new carbon-carbon bonds. It can be used to synthesize organic compounds such as alcohols, ethers, ketones, acids and esters.
The method of preparing chloride is to react 1-methyl-2-propenyl chloride with magnesium powder in an anhydrous solvent (such as dry ether). The reaction is usually carried out in an ice-water bath to avoid side reactions. After the preparation is completed, it needs to be stored in a dry environment and avoid contact with water or humid air.
When using and storing chloride, you need to pay attention to its safety information. It is an organic magnesium compound with strong activity and can react with moisture and oxygen in the air. Therefore, contact with water, moisture and oxygen must be avoided to avoid violent reactions or explosion accidents. During operation, wear protective glasses, gloves and protective clothing to ensure good indoor ventilation.
