具有三配位硅原子的稳定硅烷酮：长达一个世纪的等待结束了。

使命完成：在首次尝试分离稳定的硅烷酮100多年之后，这一任务终于随着金属硅烷酮复合物的分离而完成。 难以捉摸的裸露的Si=O键是通过利用富电子铬片段的配位球结合空间要求高的饱和N-杂环卡宾（NHC）来保护反应位点。
Mission accomplished: More than 100 years after first attempts at isolating a stable silanone, this task has finally been completed with the isolation of a metallosilanone complex. The elusive bare Si=O bond was made accessible by utilizing the coordination sphere of an electron-rich chromium fragment in combination with a sterically demanding saturated N-heterocyclic carbene (NHC) to protect the reactive site.
