Bis(pinacolato)diboron (CAS: 73183-34-3) is a fascinating organoboron compound whose chemical properties make it a cornerstone in modern synthetic organic chemistry. Understanding these characteristics is key for researchers and chemists looking to leverage its full potential in various transformations.

Chemically, Bis(pinacolato)diboron is characterized by its two pinacol boronate ester groups linked by a B-B bond. This structure confers notable stability compared to other diboron reagents, making it easier to handle, store, and use in a wider array of reaction conditions. Its relatively low melting point (137-140 °C) and good solubility in common organic solvents like toluene, THF, and hexane facilitate its integration into diverse synthetic protocols. As a supplier, we ensure that this product is maintained under optimal conditions to preserve its integrity upon delivery.

The synthetic utility of Bis(pinacolato)diboron is vast and continues to expand. Its primary role is as a nucleophilic boron source in palladium-catalyzed cross-coupling reactions, most notably the Suzuki-Miyaura coupling. This reaction allows for the formation of new carbon-carbon bonds by coupling aryl or vinyl halides with the organoboron moiety. Beyond Suzuki coupling, it is extensively used in Miyaura borylation reactions, which convert aryl halides and triflates into arylboronic esters. These transformations are fundamental in constructing complex organic molecules for pharmaceuticals, agrochemicals, and advanced materials.
