2-METHYL-1-PROPENYLMAGNESIUM BROMIDE - Introduction
bromide is an organic compound with the chemical formula C4H7BrMg.
Its main properties include:
1. appearance: colorless to light yellow liquid.
2. solubility: soluble in ether, chloroform, acetone and other organic solvents.
3. Stability: It is relatively stable under dry conditions, but it will produce hydrogen due to moisture.
The main uses of the bromide include:
1. organic synthesis: used as an important reagent in organic synthesis, can participate in the formation of carbon-carbon bonds.
2. covalent bond formation: can react with unsaturated compounds to form new carbon-carbon bonds.
3. Construction of carbon skeleton: It can be used to construct molecules containing functional groups such as alcohols, ethers, ketones and esters.
The preparation of bromide can generally be obtained by the following reactions:
methyl bromide and 3-chloropropene react in diethyl ether, and after adding magnesium powder, the reaction is obtained.
Regarding safety information, bromide should be used with caution due to its high reactivity and flammability. In operation, should wear appropriate protective equipment, maintain good ventilation conditions. Avoid contact with water, acid or oxygen to prevent the generation of flammable gases. During handling and storage, it is necessary to store it separately from other organic substances to avoid accidental reactions. If necessary, the treatment and disposal shall be carried out in accordance with the method of handling dangerous goods.
