A new type of Silicon-Boron and Silicon- Aluminum Compounds

最近，我们发现了一种成功的方法来制备含有SiH2 - alh oder (SiH2)2 Al-单元的Si-Al化合物。这类化合物还不为人所知。由于硅铝键较弱，相对于有机合成中已知的具有硅b键的化合物，可能在不添加过渡金属的催化中有应用。这些新化合物将用于硼氢化和硅氢化反应的测试。在硼方面，我们的目标是分别制备与双硅烯、硼烯和硼的环加成反应。此外，我们对小分子如AlF、BF和BF2的稳定化也很感兴趣。

Recently, we found a successful route for the preparation of Si-Al compounds containing the SiH2 –AlH oder (SiH2 )2 Al- units. This type of compounds was not known. Due to the weaker Si-Al bond, compared to the well- known compounds with Si-B bonds in organic synthesis, might have applications in catalysis without adding transition metals. The new compounds will be tested for hydroboration and hydrosilylation reactions.In the field of boron we are aiming at preparing cycloaddition reactions with bis-silylene and borenes and borines, respectively. Moreover we are interested in the stabilization of small molecules such as AlF, BF, and BF2 , respectively.
