β–二亚胺基二价稀土硼氢配合物在催化酮与硼烷硼氢化反应中的应用
摘要：
本发明公开了一种β–二亚胺基二价稀土硼氢配合物在催化硼烷与酮的硼氢化反应中的应用，利用β–二亚胺稀土二氯化物与NaBH4在四氢呋喃溶剂中反应，并通过原位Na/K还原得到β–二亚胺基二价稀土硼氢配合物：[2,6‑ipr2‑(C6H3)‑NC(Me)CHC(Me)N‑(C6H3)‑2,6‑ipr2]Ln‑BH4.2THF。本发明公开的β–二亚胺基二价稀土硼氢配合物可在温和的条件下高活性地催化硼烷与酮的硼氢化反应，具有反应时间短，反应条件温和，且后处理方法简单、方便。
摘要（英）：

The invention discloses application of a beta-diimide bivalent rare earth boron hydrogen complex in catalysis of hydroboration reaction of ketone and boron hydride. Beta-diimide rare earth dichloride and NaBH4 react in a tetrahydrofuran solvent, and in-situ Na/K reduction is carried out, so that the beta-diimide bivalent rare earth boron hydrogen complex, namely [2,6-ipr2-(C6H3)-NC(Me)CHC(Me)N-(C6H3)-2,6-ipr2]Ln-BH4.2THF, is obtained. The beta-diimide bivalent rare earth boron hydrogen complex disclosed by the invention can catalyze the hydroboration reaction of ketone and boron hydride with high activity under mild conditions and has the advantages of short reaction time and mild reaction conditions, and an aftertreatment method is simple and convenient.
