In the landscape of fine chemicals, certain reagents stand out for their versatility, reliability, and indispensable role in numerous synthetic pathways. Bis(pinacolato)diboron, identified by its CAS number 73183-34-3, is one such compound. As a leading manufacturer and supplier of high-quality chemicals in China, we understand the importance of providing comprehensive information about this crucial reagent to research scientists and procurement managers. This article delves into the key properties of Bis(pinacolato)diboron and highlights the advantages of sourcing it from a trusted Chinese manufacturer.

Bis(pinacolato)diboron, often abbreviated as B2pin2, is a white to off-white solid. Its molecular formula is C12H24B2O4, with a molecular weight of approximately 253.94 g/mol. A significant advantage of B2pin2 over many other diboron compounds is its remarkable stability. It is not particularly sensitive to moisture, which simplifies handling, storage, and integration into various reaction setups. This characteristic is highly valued by chemists who need reagents that are dependable and easy to manage in a typical laboratory environment. For organizations looking to buy chemical intermediates, this inherent stability translates to fewer complications and more consistent experimental outcomes.

Key Chemical Properties and Reactions

The utility of Bis(pinacolato)diboron stems from its unique chemical structure and reactivity. The B-B bond in B2pin2 is a source of reactive boron centers, enabling it to participate effectively in a variety of metal-catalyzed transformations. One of its most prominent applications is in palladium-catalyzed borylation reactions. This process allows for the efficient introduction of boron atoms into organic molecules, forming stable pinacolboronate esters. These esters are vital intermediates in Suzuki-Miyaura cross-coupling reactions, a cornerstone of modern synthetic organic chemistry for creating carbon-carbon bonds. Researchers commonly use B2pin2 in the synthesis of pharmaceutical building blocks, agrochemicals, and functional materials.

Furthermore, B2pin2 is instrumental in C-H activation chemistry, where transition metal catalysts mediate the direct functionalization of C-H bonds. This provides more atom-economical and step-efficient routes to complex molecules. The high purity of Bis(pinacolato)diboron, typically ≥99.0%, is critical for these catalytic processes to function optimally, ensuring high yields and minimal byproducts. Sourcing this high-purity material from a reliable manufacturer is essential for reproducible research and production.
