  Synthesis and properties of lanthanide complexes with tetrapyrazinoporphyrazine and its substituted derivatives

  摘要：

  Reactions of dicyanopyrazine and its tert-butyl-, diphenyl-, and dipyridyl-substituted derivatives with erbium, thulium, ytterbium, and lutetium chlorides, acetates, and acetylacetonates gave the corresponding tetrapyrazinoporphyrazine metal complexes which were characterized by elemental analyses, and IR, H-1 NMR, and electronic absorption spectra. The stability of the complexes to thermooxidative decomposition in air was also studied.

• Electrochemistry of lanthanoid(III) complexes in dimethyl sulfoxide in the presence of n-Bu4N(acac) and n-Bu4N(dibm)

  DOI：10.1016/0013-4686(90)87070-i

  日期：1990.11

  lanthanoid Ln(III) complexes was investigated in Me2SO including n-Bu4N(acac) and n-Bu4N(dibm) as ligands (where acac is the acetylacetonate anion and dibm is the diisobutrylmethanate anion). Reversible one electron reduction waves corresponding to Ln(III) complexes→Ln(II) complexes were observed in the concentration range of 5–20 mM of the ligands, including 1 mM lanthanoid perchlorates and 0.1 M TEAP

  镧系LN（III）络合物的电化学行为在我研究了2 SO包括Ñ -Bu 4 N（ACAC）和Ñ -Bu 4 N（dibm）作为配体（其中ACAC是乙酰丙酮化物阴离子和dibm是diisobutrylmethanate阴离子） 。在5–20 mM的配体浓度范围内观察到了对应于Ln（III）配合物→Ln（II）配合物的可逆的一个电子还原波，包括1 mM镧系高氯酸盐和0.1 M TEAP。在存在5 mM配体的情况下，在0.1 M TEAP中，镧系元素络合物的半波电势为sce -1.66至-2.61 V ，具体取决于镧系元素（III）离子。

  本发明公开了一种二茂铁修饰的稀土金属卟啉光催化剂、制备方法及其应用。本发明首先通过以四羟基卟啉、二茂铁甲酸为原料，苯为溶剂，进行酯化反应，得到二茂铁酯基卟啉配体；接着以稀土乙酰丙酮配合物和二茂铁酯基卟啉配体为原料，1,2,4‑三氯苯为溶剂，在保护性气体氛围下进行配位反应，制备了二茂铁修饰的稀土金属卟啉光催化剂；该二茂铁修饰的稀土金属卟啉光催化剂应用于催化二氧化碳和环氧化物进行环加成反应时表现出优异的催化效果，同时获得了较高产率的环状碳酸酯。
• Synergism by sublimation of volatile lanthanide β-diketonates

  日期：2000.8

  The synergistic effect by sublimation manifests itself in an increase in the volatility of nonvolatile or slightly volatile compounds in the presence of highly volatile agents. In this study, manifestations of the synergistic effect are demonstrated by the evaporation of mixed ligand complexes, derivatives of lanthanide acetylacetonates and neutral organic ligands, and by evaporation of the following mixtures: yttrium and zirconium acetylacetonates, lanthanum and nickel dipivaloylmethanates and acetylacetonates, and lanthanum and aluminum acetylacetonates.

• LANTHANIDE COMPLEXES WITH ACETYLACETONATE AND 5,10,15,20-TETRA[<i>PARA</i>-(4-FLUOROBENZOYLOXY)-<i>META</i>-METHOXY]PHENYLPORPHYRIN

  Lanthanide complexes of acetylacetonate and 5,10,15,20-tetra [para-(4-fluorobenzoyloxy)-meta-methoxy]phenylporphyrin having the general formula Ln[(FBOMP)(4)P](acac) (where Ln=Er, Tm, Yb; FBOMP=[para-(4-fluorobenzoyloxy)meta-methoxy]phenyl; acac=acetylacetone; P=porphyrin) have been prepared and characterized. A structure is proposed in which one 5,10,15,20-tetra[para-(4-fluorobenzoyloxy)meta-methoxy]porphyrin molecule is coordinated to a rare earth ion in a tetradentate fashion, while one acetylacetonate molecule is coordinated to the same metal ion in a bidentate fashion.
