Abstract
We report the first diarylborane-catalysed hydrosilylation of epoxides and cyclic ethers. Mechanistic studies on the in situ generated Piers' borane (C6F5)2BH with hydrosilanes in the presence of an epoxide revealed that an alkyloxy(diaryl)borane (C6F5)2BOR is readily formed as a catalytically competent species for the outer-sphere hydrosilylation of epoxides and cyclic ethers.
摘要
我们报道了首例二芳基硼烷催化的环氧化合物和环醚的硅氢化反应。在环氧化合物存在下，原位生成的 Piers 硼烷（C6F5）2BH 与硅烷的反应的机理研究表明，烷氧基（二芳基）硼烷（C6F5）2BOR 很容易形成，是一种催化活性物种，可用于环氧化合物和环醚的外球硅氢化反应。
