摘要

首先合成了（三氟甲基）四甲基钌烯基镍螯合物NiC1[{2,5-(R2PCH2)2C5H2}Ru(CpF)] (CpF = C5Me4CF3, R = But （3a), Pri (3b)）。研究了配合物3a与NaBH4的反应。得到的二膦二硼烷化合物{1,3-(H3B-P(But)2CH2)2C5H3}Ru(CpF)(4)代替了预期的反应产物Ni(BH4)[{2,5-(But2PCH2)2C5H2}Ru(CpF)]。化合物3a、3b和4经核磁共振谱完全表征。通过单晶x射线衍射确定了化合物3a和4的结构。

New ruthenocene-based nickel pincer complexes bearing the C5Me4CF3 ligand

First (trifluoromethyl)tetramethylruthenocene-based nickel pincer complexes NiC1[{2,5-(R₂PCH₂)₂C₅H₂}Ru(Cp^F)] (Cp^F = C₅Me₄CF₃, R = Bu^t (3a), Prⁱ (3b)) were synthesized. The reaction of complex 3a with NaBH₄ was investigated. The diphosphine diborane compound {1,3-(H₃B-P(Bu^t)₂CH₂)₂C₅H₃}Ru(Cp^F) (4) was obtained instead of the expected reaction product Ni(BH₄)[{2,5-(Bu^t₂PCH₂)₂C₅H₂}Ru(Cp^F)]. Compounds 3a, 3b, and 4 were fully characterized by NMR spectroscopy. The structures of compounds 3a and 4 were established by single-crystal X-ray diffraction.
