Following the successful syntheses of Lewis base stabilized Si2H2 and Si3 - molecules, we are looking forward to extend the chemistry of these molecules while using alternative Lewis bases.The reaction of Si2H2 and Si3 molecules with cAACSiSicAAC should give the Si5(cAAC)5 and (cAAC)4Si4SiH2 compounds, respectively. Furthermore we are aiming at preparing mixed hydride R silylene species of composition HSiR:. An important part of the investigations is focused on the preparation of stable radicals of silicon and aluminium. The reduction of Me2SiCl2 und Me(H)SiCl2, respectively in the presence of cAAC should lead to stable radicals in the coordination sphere of silicon. Finally the preparation of compounds with aluminium-silicon bonds and asymmetric compounds with Al-Al bonds will be extensively studied.

在成功合成了刘易斯碱稳定的Si 2 H2和Si 3-分子之后，我们期待着在使用替代的刘易斯碱时扩展这些分子的化学性质。此外，我们的目标是制备组成为HSiR：的混合氢化物R亚甲硅烷基物质。调查的一个重要部分是集中在硅和铝的稳定自由基的制备。Me 2SiCl 2和Me（H）SiCl 2分别在cAAC存在下的还原应在硅的配位层中产生稳定的自由基。最后，对含铝硅键化合物和含铝铝键的不对称化合物的制备进行了广泛的研究。
