Stabilization of reactive small molecules of silicon and aluminum through coordination of heterocyclic carbenes

随着路易斯碱稳定Si2H2和Si3 -分子的成功合成，我们期待着在使用替代路易斯碱的同时扩展这些分子的化学性质。Si2H2和Si3分子与cAACSiSicAAC反应分别生成Si5(cAAC)5和（cAAC）4Si4SiH2化合物。此外，我们的目标是制备混合氢化物R硅炔组分HSiR：。研究的一个重要部分是硅和铝的稳定自由基的制备。在cAAC的存在下，Me2SiCl2和Me(H)SiCl2的还原反应会在硅的配位球中产生稳定的自由基。最后对铝硅键化合物和Al-Al键不对称化合物的制备进行了广泛的研究。

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.
