Synthesis, structure and catalytic behavior of ytterbium complexes bearing a phenoxy(quinolinyl)amide ligand

Journal of Rare Earths 2012年第9期30卷 909-915页

作者：朱曦王耀荣姚英明吴冰沈琪 Key Laboratory of Organic Synthesis of Jiangsu Province College of ChemistryChemical Engineering and Materials ScienceSoochow University

Two ytterbium complexes stabilized by phenoxy（quinolinyl）amide ligand 3,5-But2-2-OC6H2CH2N-8-C9H6N （L） were synthesized and characterized. Reaction of anhydrous YbC13 with 1 equiv, of LLi2 in THF gave the ytterbium chloride [LYbCI（THF）]2 （1） in 73% yield. A further reaction of complex 1 with equimolar of NaN（SiMe3）2 in THF afforded the unexpected heterobimetallic ＂ate＂-complex L2YbNa（THF）2 （2） via a ligand redistribution reaction. complex 2 could also be prepared in high isolated yield by the reaction of anhydrous YbC13 with 2 equiv, of LNa2 generated in situ. Both complexes 1 and 2 were characterized by IR spectroscopy, elemental analysis, and sin- gle-crystal X-ray diffraction analysis. It was found that complex 2 was an effective catalyst for the addition reaction of aromatic amines to carbodiimides.

Chinese Journal of Structural Chemistry 2009年第5期28卷 565-568页

作者：段泰轲许超冯妍张千峰 Institute of Molecular Engineering and Applied Chemistry Anhui University of TechnologyMa'anshan Anhui 243002 China Institute of Molecular Engineering and Applied Chemistry Anhui University of TechnologyMa’anshan Anhui 243002 China

A novel hexanuclear copper-indium thiolate complex, [（InCl）2（OMe）（μ-OMe）2（μ- OMe）（μ-SPrn）2（CuPPh3）]2 1, was synthesized from the reaction of NaSPrn, InCl3 and [Cu（Me- CN）a][PF6] in the presence of Ph3P and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P211n with a = 11.3533（8）, b = 15.4939（11）, c = 20.5189（14） A, β = 98.577（2）°, V = 3569.0（4） A3, Z = 2, C56H82Cl4Cu2In4O8P2S4, Mr = 1801.56, Dc = 1.676 g/cm3,μ（MoKa） = 2.213 mm^-1, F（000） = 1796, S = 0.985, the final R = 0.0559 and wR = 0.1099 for 8878 observed reflections with I 〉 2σ（I） and 367 variables. complex 1 consists of two CuPPh3 fragments which symmetrically side-attach to the tetranuclear core of [InaCl4（OMe）2（μ-OMe）a（μ- OMe）2（μ-SPrn）4] by coordinating with sulfur atoms of propane-thio moieties. The average In-Ot （terminal）, In-μ-O and In-μ3-O bond distances are 2.305（4）, 2.144（4） and 2.294（4） A, respectively.
