The reaction of the six-vertex amido-substituted silicon cluster Si{N(SiMe)Ph} 1 with two equiv. of KC results in the abstraction of K{N(SiMe)Ph} and leads to the contact ion pair 2 including an anionic silicon cluster with two unsubstituted pyramidal vertices. Facile functionalization of 2 was achieved with MeI, SiCl and SiBr and results in neutral two-fold functionalized silicon clusters.
六顶点氨基取代的硅簇合物Si{N(SiMe)Ph}₆ 1与两当量的KC反应，导致K{N(SiMe)Ph}被夺取，并生成接触离子对2，其中包括一个带有两个未取代金字塔形顶点的阴离子硅簇。通过MeI、SiCl和SiBr实现了2的简便官能化，得到了中性的双官能化硅簇。
