and fully characterized (multinuclear NMR, IR, UV/vis spectroscopy, mass spectrometry). The thermodynamics of this interaction was studied by DFT calculations, indicating several possible ways of synthesis of unexpected 4 and 5, which are obtained under rupture and formation of new Si Si bonds. The molecular structure of 3 was studied by single crystal XRD analysis.
摘要
有机锂试剂 (η6-
C6H5Li)Cr(CO)3 (1-Li) 与 ClSiMe2SiMe2Cl (2) 的相互作用导致 [(OC)3Cr(η6-
C6H5)]SiMe2SiMe2[(η6- )Cr(CO)3 ] (3), Me2Si[(η6- )Cr(CO)3]2 (4) 和 [(OC)3Cr(η6- )][SiMe2]4[(η6- )Cr(CO)3] (5); 化合物 3 和 4 以制备产率分离并完全表征(多核 NMR、IR、UV/vis 光谱、质谱)。通过 DFT 计算研究了这种相互作用的热力学,表明了几种可能的合成 4 和 5 的可能方式,它们是在断裂和形成新的 Si Si 键的情况下获得的。通过单晶XRD分析研究了3的分子结构。
