4-METHYLBENZYLMAGNESIUM CHLORIDE - Introduction
4-Methylbenzylmagnesium chloride is an organic magnesium compound with the chemical formula of C≡H∞CH₂ CH₂ CH₂ MgCl. It has the following properties and uses:
Nature:
1. Appearance: 4-Methylbenzylmagnesium chloride is a colorless to pale yellow liquid.
2. flammability: It is flammable and needs to be stored away from the fire source.
3. Solubility: It is soluble in ethers, solvents and ethanol and other non-polar solvents.
Use:
1. organic synthesis: 4-Methylbenzylmagnesium chloride is commonly used as a reagent in organic synthesis reactions, for example, it reacts with aldehydes, ketones and other compounds to generate corresponding alcohols or acids in Grignard reactions.
2. Dehydrogenation and condensation reactions: It can be used to dehydrogenate alcohols to produce corresponding olefins, or to condense with other organic compounds to produce carbon-carbon bonds.
Preparation Method:
4-Methylbenzylmagnesium chloride can be prepared by reacting benzyl magnesium chloride with methyl bromide or methyl chloride. First, benzyl magnesium chloride is reacted with a methylating agent in a solvent such as anhydrous ether or dichloromethane to generate the target product.
Safety Information:
1. 4-Methylbenzylmagnesium is chloride irritating to the skin and eyes. Appropriate protective gloves and goggles should be worn when using it.
2. Due to its flammability, it should be stored away from fire and high temperature, and avoid contact with oxygen.
3. when in use, should be operated in a well-ventilated environment, avoid inhalation of its steam.
4. For the remaining unused reagents, they should be properly sealed and stored, away from moisture and air, and avoid reacting with moisture in the air.
