Abstract
Oligosilanes with attached silatranyl units were obtained by reactions of potassium oligosilanides with a silatranyl triflate. Interaction between Si and N atoms was observed in the Si NMR spectra (upfield-shifted SiO resonances) and in the solid-state structures (Si-N distances between 2.29 and 2.16 Å). The Si-N interaction can be "switched off" either by protonation of the nitrogen lone pair or by potassium silanide formation caused by trimethylsilyl group cleavage in the presence of potassium -butoxide.
摘要
通过低聚硅烷钾与三氟甲磺酸硅杂环戊二烯酯的反应，得到了带有硅杂环戊二烯基单元的低聚硅烷。在硅核磁共振谱（SiO共振峰向高场位移）和固态结构（Si-N距离在2.29至2.16 Å之间）中观察到了Si与N原子之间的相互作用。Si-N相互作用可以通过氮孤对的质子化或在叔丁醇钾存在下三甲基硅基裂解导致的硅烷钾形成来“关闭”。
