CAS 126689-01-8: Cyclopropylboronic acid pinacol ester

Description: Cyclopropylboronic acid pinacol ester is an organoboron compound characterized by the presence of a cyclopropyl group attached to a boronic acid moiety, which is further esterified with pinacol. This compound typically exhibits a white to off-white solid appearance and is soluble in organic solvents such as dichloromethane and ethanol. It is known for its reactivity in various organic synthesis applications, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a versatile building block for the formation of carbon-carbon bonds. The boronic acid functionality allows for the formation of stable complexes with diols and other Lewis bases, enhancing its utility in synthetic chemistry. Additionally, cyclopropylboronic acid pinacol ester can be sensitive to moisture and air, necessitating careful handling and storage under inert conditions. Its unique structural features and reactivity make it a valuable compound in the development of pharmaceuticals and advanced materials.
