Beschreibung

Employed in organic synthesis. Addition of catecholborane to vinylarenes in the presence of Wilkinson's catalyst, gives Markovnikov hydroboration products exclusively, whereas the corresponding reaction with a-substituted vinylarenesgivesgood yields of vinylboronate. Hydroboration with catecholborane, followed by treatment with easily available reagents such as alkenyl sulfones or alkynyl phenyl sulfones in the presence of a radical initiator, represents an effective and simple one-pot procedure for direct vinylation, formylation, and cyanation. Catecholborane may be used as a stereoselective reducing agent when converting β-hydroxy ketones to syn 1,3-diols. 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.
