Novel functional groups of low-valent silicon

点击翻译按钮获取中文摘要

Low-valent silicon compounds are valuable building blocks for the synthesis of novel functional groups which continue to attract considerable attention in main group chemistry. The objectives of the project are the synthesis and investigation of the reactivity of unprecedented isolable low-valent silicon compounds featuring silicon(0), silicon(II) and silicon multiply bonded sites. Central objectives are the generation of silicon-oxygen multiply bonded compounds such as silanones with three-coordinate silicon atoms, NHC-stabilized monomeric silicon dioxide and silicon monoxide, NHC-supported :Si=PH, :Si=NH, :Si=C: species as well as low-valent silicon and NHC supported zero-valent metal complexes thereof.
