4-Methoxyphenylboronic acid

Description:

4-Methoxyphenylboronic acid, with the CAS number 5720-07-0, is an organoboron compound characterized by the presence of a boronic acid functional group attached to a methoxy-substituted phenyl ring. This compound typically appears as a white to off-white solid and is soluble in polar organic solvents such as methanol and ethanol. It is known for its ability to form reversible covalent bonds with diols, making it useful in various applications, including organic synthesis and as a reagent in Suzuki coupling reactions, which are pivotal in the formation of carbon-carbon bonds. The methoxy group enhances the electron density of the aromatic ring, influencing its reactivity and stability. Additionally, 4-methoxyphenylboronic acid can serve as a building block in the synthesis of pharmaceuticals and agrochemicals. Its boronic acid functionality allows for the formation of complexes with biomolecules, which has implications in medicinal chemistry and materials science. Proper handling and storage are essential due to its reactivity and potential environmental impact.

4-Methoxyphenyl boronic acid

CAS: 5720-07-0

4-Methoxyphenyl boronic acid is a molecule with a hydroxyl group and a boronic acid. It is synthesized by reacting biphenyl with trifluoroacetic acid in the presence of sodium carbonate and palladium-catalyzed coupling. 4-Methoxyphenyl boronic acid has shown to bind to the receptor for fatty acids, which may be due to its structural similarity to p-hydroxybenzoic acid. The protonated form of this molecule has been shown to react with an electrophilic carbon atom and an electron-deficient alkyl or vinyl halide, resulting in ring formation. This reaction is known as the Suzuki coupling reaction.
