4-Ethyl-trans-beta-styrylboronic acid pinacol ester

Description:
4-Ethyl-trans-beta-styrylboronic acid pinacol ester is an organoboron compound characterized by the presence of a boronic acid functional group, which is typically used in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling. This compound features a trans-styryl moiety, which contributes to its geometric isomerism, and an ethyl substituent that can influence its solubility and reactivity. The pinacol ester formation enhances the stability of the boronic acid, making it more suitable for various synthetic applications. Generally, boronic esters like this one are known for their ability to form stable complexes with diols and are utilized in the development of pharmaceuticals and agrochemicals. The compound's reactivity can be modulated by the electronic and steric effects of the substituents, making it a valuable intermediate in the synthesis of more complex molecules. Additionally, its properties, such as solubility and stability, can vary depending on the solvent and reaction conditions employed.
