摘要/Abstract

有关异腈酸酯硼氢化反应的报道极其稀少, 迄今为止, 锌金属化合物催化的异腈酸酯硼氢化反应尚未见报道. 介绍了一种结构新颖的不对称 β-二亚胺锌-锂双金属化合物的合成方法, 并将其作为高效催化剂成功应用于一系列带有不同官能团的异腈酸酯和频哪醇硼烷的硼氢化反应中, 同时对硼氢化反应机理进行了初步探索.

There are very few reports on the isocyanate hydroboration. So far, the Zn-catalyzed hydroboration of isocyanate has not been reported. The synthesis of a novel asymmetric β-diketiminate Zn-Li bimetallic compound and its application as a highly efficient catalyst in the hydroboration of various isocyanates with HBpin in high yields are reported. The preliminary mechanism of hydroboration reaction has been explored.
Key words: Zn-Li bimetallic compound, isocyanate, hydroboration, synthesis
