926-62-5 - Introduction
isobutylmagnesium bromide is an organometallic compound with the chemical formula (CH3)2 CHCH2MgBr. The following is a description of the nature, use, preparation and safety information of isobutylmagnesium bromide:
Nature:
-Appearance is colorless or light yellow liquid.
-Soluble in organic solvents such as ethers and hydrocarbons.
-It has a high degree of humidity sensitivity in the air and is easy to decompose.
Use:
- isobutylmagnesium bromide is an important reagent in organic synthesis and can be used to synthesize various organic compounds, such as alcohols, ethers, ketones, carboxylic acids, etc.
-It can be used as an addition reagent, nucleophile, reducing agent and filler of alkenes and alkynes.
Method:
The preparation of isobutylmagnesium bromide is usually carried out by the following steps:
1. Dissolve isobutyl lithium in anhydrous ether.
2. slowly drop magnesium bromide at low temperature.
3. After completion of the reaction, a isobutylmagnesium bromide solution was obtained.
Safety Information:
- isobutylmagnesium bromide are highly moisture sensitive and should be stored and handled under the protection of inert gas.
-Because it is an organometallic compound, it is dangerous and volatile for non-professionals, so you need to be careful and take appropriate safety measures when using it.
