Description
Bis(pinacolato)diboron is a reagent used for the cis-vicinal diborylation of acetylenes and olefins with platinum catalysis. It acts as a substrate used in a new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates. It is used as a condensation agent in the preparation of poly(arylene)s. It plays an essential role in Suzuki reaction and used as matrix metallo-proteinase (MMP-2) inhibitor.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
