MAGNESIUM DIBUTYL - Introduction
n-Butyl-sec-butylmagnesium, the chemical formula is (CH2CH2CH2CH2) 2CHMg, which is often abbreviated as n-Bu-MgBr or n-Bu2Mg. It is an organic magnesium reagent with the following properties:
1. Nature: n-Butyl-sec-butylmagnesium is a solid, white crystal or powder at room temperature. It can be dissolved in non-polar solvents such as anhydrous ether, and can react with polar solvents such as alcohols and ketones. It is an alkaline reagent with strong reducibility and nucleophilicity.
2. Use: n-Butyl-sec-butylmagnesium is commonly used in organic synthesis reagents, can be used for the synthesis of a variety of organic compounds. In particular, it is commonly used in the Grignard reaction, can be substituted with carbonyl compounds to produce Alcohols, Ketones and other organic compounds. In addition, it can also be used for the synthesis of hydrocarbons, alcohols, aldehydes, ketones and other organic compounds, and can be used as an intermediate for the preparation of magnesium enyne compounds.
3. Preparation method: the preparation of n-Butyl-sec-butylmagnesium generally adopts the method of direct synthesis, that is, butyl magnesium bromide reacts with SEC-butyl bromide to generate the product. The specific preparation method is as follows: under anhydrous conditions, butyl magnesium bromide and SEC-butyl bromide are reacted together with an appropriate amount of solvent (such as tetraethyl ether, dimethylformamide) to generate n-Butyl-sec-butylmagnesium.
4. Safety Information: n-Butyl-sec-butylmagnesium is a kind of organic magnesium reagent, has certain risk. During operation, attention should be paid to avoid contact with water, oxygen and other substances that react with it to avoid fire or explosion. In addition, it is irritating to the skin and eyes, and care should be taken to avoid contact. When in use, take appropriate protective measures, such as wearing protective glasses, gloves and protective clothing, and good ventilation. During storage, it should be stored in a dry, ventilated and away from fire sources, avoiding contact with air or moisture. If there is a mistake or accident, should be timely medical treatment.
