Beschreibung

Anwendung

A monofunctional hydroborating agent which reduces β-hydroxyketones to 1,3-diols. Effects conjugate reduction of α,β-enones.

Used to prepare B-alkylcatecholboranes which were used, in turn, to generate alkyl radicals forming aryl ethers from quinones. Employed in a preparation of C2-symmetric boron complexes from methylenebis(oxazolines) used for enantioselective reduction of ketones.
