produced different kinds of rare earth metal complexes. Complexes incorporating amido and enolate mixed ligands having the general formula (CH2 CHO)Ln[2,6-(iPr)2C6H3NSiMe3]2(μ-Cl)Li(THF)3 (Ln = Y(1), Yb(2)) were prepared by the reaction of N-trimethylsilyl-2,6-diisopropylaniline 2,6-(iPr)2C6H3NHSiMe3 with excess nBuLi in THF, followed by treatment with LnCl3. Complexes with the formula [2,6-(Et)2C
摘要2,6-(R)2C6H3NHSiMe3(R = iPr或Et)与过量的nBuLi在THF或正己烷中的反应,然后用LnCl3处理,生成了各种稀土金属络合物。包含具有通式(CH2 CHO)Ln [2,6-(iPr)2C6H3NSiMe3] 2(μ-Cl)Li(THF)3(Ln = Y(1),Yb(2))的酰胺基和烯醇盐混合配体的配合物通过使N-三甲基甲硅烷基-2,6-二异丙基苯胺2,6-(iPr)2C6H3NHSiMe3与过量的nBuLi在THF中反应,然后用LnCl3处理来制备。具有式[2,6-(Et)2C6H3NSiMe3] 2Y(THF)(μ-Cl)2Li(THF)2(3)和[2,6-(Et)2C6H3NSiMe3] 3YCl} [Li(THF)的配合物[4] [4]的分离方法是,将2,6-(Et)2C6H3NHSiMe3用正己烷中的nBuLi处理,然后用1/2或1/3当量处理。分别在THF中的YCl
