p-Tolylmagnesium bromide

Description:
p-Tolylmagnesium bromide, with the CAS number 4294-57-9, is an organomagnesium compound classified as a Grignard reagent. It is characterized by the presence of a p-tolyl group (a methyl-substituted phenyl group) bonded to a magnesium atom, which is further associated with a bromide ion. This compound typically appears as a colorless to light yellow solution when dissolved in ether or other suitable solvents. p-Tolylmagnesium bromide is highly reactive, particularly with water and protic solvents, leading to the release of hydrocarbons and the formation of magnesium hydroxide. It is commonly used in organic synthesis for nucleophilic addition reactions, allowing for the formation of carbon-carbon bonds. The reactivity of this Grignard reagent makes it valuable in the preparation of various organic compounds, including alcohols and other functionalized molecules. Due to its reactivity, it must be handled under anhydrous conditions to prevent decomposition and ensure successful reactions.

    CAS:
    <p>p-Tolylmagnesium Bromide is a Grignard reagent that is used in organic synthesis. It can be used to synthesize new compounds and is an important reagent in the palladium-catalyzed cross-coupling reaction. In this reaction, the Grignard reagent reacts with a halide to form an organometallic intermediate. The nucleophile (typically an alcohol) then attacks the carbon atom of the organometallic intermediate, displacing one of its bromine atoms and forming a new carbon-carbon bond. The magnesium can also be replaced by other metals such as zinc or lithium. p-Tolylmagnesium Bromide is often used as a catalyst for cationic polymerization reactions. It is also used to remove chlorine from chlorides, fluorine from fluoroalkanes, sulfides from sulfoxides, and tosylates from tosylate esters. p-Tolylmagnesium Bromide has</p>
