Herein, we report the stabilization of lithium-ion as the source of lithium to use as a trans-metalation reagent [{PhC(N Bu) Si( Bu)Li} I( BuN) CPh] (1). The reaction of 3 equivalents of the LSi Bu (L=PhC(N Bu) ) and lithium iodide at low temperature leads to a silylene stabilized lithium-ion with an additional coordination of amidinate ligand. Compound 1 shows two four membered and one six membered ring as confirmed by QTAIM calculations. Whereas the reaction of the LSiCl with 1.5 equivalents of carbodiimide (CyN) C at room temperature affords compound [PhC(N Bu) Si(Cl)(NCy) NCy] (2) with the CN SiN C skeleton containing silicon as a central atom. Both the compounds were fully characterized by NMR, mass spectrometry, X-ray crystallographic analysis, and quantum mechanical calculations.
在此，我们报道了将锂离子稳定化作为锂源，用作转金属化试剂[{PhC(NBu)Si(Bu)Li}I(BuN)CPh] (1)。3当量的LSiBu (L = PhC(NBu))与碘化锂在低温下反应，生成一种由甲脒配体额外配位的硅烯稳定化锂离子。通过QTAIM计算证实，化合物1显示出两个四元环和一个六元环。而LSiCl与1.5当量的碳二亚胺(CyN)C在室温下反应，得到化合物[PhC(NBu)Si(Cl)(NCy)NCy] (2)，其CNSiNC骨架以硅为中心原子。这两种化合物均通过核磁共振、质谱、X射线晶体学分析和量子力学计算进行了全面表征。
