O-TOLYLMAGNESIUM BROMIDE - Introduction
O-tolylmagnesium bromide(O-tolylmagnesium bromide) is an organic compound with the chemical formula C7H7BrMg. It is a colorless to light yellow liquid with a strong pungent odor at room temperature.
O-tolylmagnesium bromide are mainly used as reagents in organic synthesis. It can react with acyl halides, ketones, aldehydes, etc. for alkylation, acylation, and alkyl quinone synthesis. It can also react with halogenated hydrocarbons to form o-tolyl alkoxides, which are often used in the synthesis of organic compounds containing tolyl.
There are several methods for the preparation of O-tolylmagnesium bromide. The common method is to add bromotoluene dropwise to magnesium powder. Inert solvents such as dimethylformamide (DMF) or tetrahydrofuran (THF) are commonly used to promote the reaction. After completion of the reaction, a suspended solid precipitates in the solution, and a O-tolylmagnesium bromide can be obtained after filtration.
When using O-tolylmagnesium bromide, you need to pay attention to its irritation and toxicity, and avoid contact with skin and eyes. Wear appropriate protective equipment such as protective gloves, goggles and protective clothing during operation. At the same time, it should be operated in a well-ventilated place to avoid inhaling its vapor.
In general, O-tolylmagnesium bromide is an important organic reagent and has a wide range of applications in organic synthesis, but it is necessary to pay attention to safe operation when using it.
