3-ethynylphenylboronic acid

Description:
3-Ethynylphenylboronic acid is an organoboron compound characterized by the presence of a boronic acid functional group attached to a phenyl ring that is further substituted with an ethynyl group. This compound typically exhibits properties such as being a white to off-white solid, soluble in polar organic solvents, and possessing moderate stability under standard conditions. The boronic acid moiety allows for reversible interactions with diols, making it useful in various applications, including organic synthesis and medicinal chemistry, particularly in the development of boron-containing drugs. The ethynyl group contributes to its reactivity, enabling participation in cross-coupling reactions, such as Suzuki-Miyaura coupling, which is a key method for forming carbon-carbon bonds. Additionally, 3-ethynylphenylboronic acid may exhibit interesting electronic properties due to the conjugation between the ethynyl group and the aromatic system, potentially influencing its behavior in electronic applications. Overall, this compound serves as a valuable building block in the synthesis of more complex organic molecules.
