Preparation method of diisopropylamine silane

The invention provides a preparation method of diisopropylamine silane, and belongs to the field of organic synthesis. The preparation method of diisopropylamine silane provided by the invention comprises the following steps: in the presence of a first catalyst, # imgabs0 # reacts with pinacol borane to form diisopropylamine silane and pinacol phenylboronic acid ester, and the first catalyst is borane or a solution thereof. According to the preparation method of the diisopropylamine silane, on one hand, separation and purification are easy, on the other hand, the reaction has high selectivity, and generation of by-products is greatly reduced. 本发明提供了一种二异丙胺硅烷的制备方法，属于有机合成领域。本发明提供的二异丙胺硅烷的制备方法，包括如下步骤：在第一催化剂存在下，#imgabs0#与频那醇硼烷反应形成二异丙胺硅烷和苯硼酸频那醇酯，其中，所述第一催化剂为硼烷或其溶液。本发明提供的二异丙胺硅烷的制备方法一方面分离提纯比较容易，另一方面反应具有很高的选择性，大大减少了副产物的产生。
