Novel functional groups of low-valent silicon

低价硅化合物是合成新型官能团的重要组成部分，在主基团化学中一直备受关注。该项目的目标是合成和研究具有硅(0)，硅（II）和硅多重键位的前所未有的可分离的低价硅化合物的反应性。中心目标是生成硅氧多键化合物，如具有三坐标硅原子的硅酮，NHC稳定的单体二氧化硅和一氧化硅，NHC支持的：Si=PH,:Si=NH,:Si=C，以及低价硅和NHC支持的零价金属配合物。

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.
