DETAILS

Description (English)

Application
A monofunctional hydroborating agent which reduces β-hydroxyketones to 1,3-diols.1 Effects conjugate reduction of α,β-enones.2
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.
Packaging

Description (简体中文)

Application
单官能硼氢化试剂，可将 β-羟基酮还原为 1,3-二醇。1可影响 α,β-烯酮共轭还原反应。2
用于制备 B-烷基儿茶酚硼烷，B-烷基儿茶酚硼烷又可产生烷基自由基，与醌作用形成芳基醚。可用于与亚甲基双(噁唑啉)作用制备 C2-对称硼络合物，亚甲基双(噁唑啉)还可用于酮的不对称还原反应。
