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.

最近，我们发现了一条制备含SiH_2-AlH或（SiH_2）_2Al-单元的Si-Al化合物的成功路线。这种类型的化合物是未知的。由于Si-Al键较弱，与有机合成中已知的具有Si-B键的化合物相比，可能在不添加过渡金属的催化中具有应用。新化合物将进行硼氢化和硅氢化反应的测试。在硼领域，我们的目标是分别与双硅烯和硼烯和硼烯进行环加成反应。此外，我们感兴趣的小分子，如AlF，BF和BF 2，分别稳定。
