β-Bromostyrene

Description:

β-Bromostyrene is an organic compound characterized by its structure, which features a bromine atom attached to the β-carbon of a styrene molecule. It is a colorless to pale yellow liquid with a characteristic aromatic odor. This compound is known for its reactivity, particularly in electrophilic substitution reactions due to the presence of the bromine atom, which can facilitate further chemical transformations. β-Bromostyrene is used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals and agrochemicals. It exhibits moderate solubility in organic solvents and is relatively stable under standard conditions, although it can undergo polymerization. Safety precautions are necessary when handling β-bromostyrene, as it can be harmful if inhaled or absorbed through the skin, and it may pose environmental hazards. Proper storage in a cool, dry place away from light is recommended to maintain its stability and prevent degradation.

β-Bromostyrene

CAS: 103-64-0

β-Bromostyrene is a halogenated aromatic hydrocarbon that has been used as a cross-coupling reagent. β-Bromostyrene reacts with an organometallic reagent to form a new carbon-carbon bond. This reaction is catalyzed by palladium, which is often dissolved in the reaction vessel along with the β-bromostyrene and the organometallic reagent. The palladium enhances the rate of this reaction by increasing the concentration of reactive molecules, while also acting as a catalyst for the coupling of two organic molecules. β-Bromostyrene has been shown to be useful in wastewater treatment, where it reacts with organic compounds such as benzene, toluene, and xylene to form water soluble products called bromoxylates.
The detection sensitivity of β-bromostyrene can be increased through its use as an indicator for pH changes in acidic environments (pH 3). The
