Descrizione

CAS: 25015-63-8 | C6H13BO2 | 127.98 g/mol

Pinacolborane is used as a precursor of boronic esters by hydroboration or coupling reactions. It acts as a monofunctional hydroborating agent. It is used in the synthesis of unsymmetrical biaryls through aromatic C-H borylation-cross-coupling sequence. It is involved in the preparation of 4,4,5,5-tetramethyl-2-thiophen-2-yl-[1,3,2]dioxaborolane by reacting with 2-iodo-thiophene. Further, it is used to prepare vinylboronates by palladium-catalyzed coupling with alkenyl triflates and iodides.

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.
