    摘要:
    A convenient and practical method is proposed for the synthesis of lanthanide and yttrium alkoxides. The method involves dissolving the metals or their hydrides in a solution of dry HCl in the corresponding alcohol, with subsequent dehalogenation of the LnCl3 solution by an equivalent amount of alkali metal (Na, Li), The rare-earth alkoxides are easily converted into acetylacetonates Ln(acac)3 by the action of acetylacetone.

  • Electrochemistry of lanthanoid(III) complexes in dimethyl sulfoxide in the presence of n-Bu4N(acac) and n-Bu4N(dibm)
    作者:Akio Iwase、Yoshinori Araki、Reiko Takahashi

    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。
  • Selective one-step synthesis of triple-decker (porphyrinato)(phthalocyaninato) early lanthanides: the balance of concurrent processes

    An effective one-step approach for the preparation of (porphyrinato)(phthalocyaninato) early lanthanides of type [Br4TPP]Ln[(15C5)4Pc]Ln[Br4TPP], where Br4TPP = 5,10,15,20-tetrakis-(4-bromophenyl)-porphyrinato-ligand, (15C5)4Pc = tetrakis-(15-crown-5)-phthalocyaninato-ligand and Ln = La, Pr, Nd or Eu, is developed. The influence of various factors on the reaction pathway and yields of the complexes is investigated in detail. The developed protocol is found to be general for the early lanthanide subgroup. Variation of the synthetic conditions allowed the determination and isolation of possible side-products, namely heteroleptic double-deckers [Br4TPP]Ln[(15C5)4Pc] (Ln = Nd, Eu) and triple-decker [Br4TPP]Nd[(15C5)4Pc]Nd[(15C5)4Pc]. The peculiarities of the NMR lanthanide-induced shifts (LIS) of resonances of the synthesized triple-decker complexes are precisely investigated. The isostructurality of the synthesized complexes within the series as well as isostructurality with previously synthesized compounds is demonstrated in terms of two-nuclei analysis of LIS.

    The triple-decker complexes of symmetrical type [m Br 4 TPP ] Ln [(15 C 5)4 Pc ] Ln [m Br 4 TPP ] ( Ln -m TD ; Ln = La , Nd ; [(15 C 5)4 Pc ] = tetra-(15-crown-5)-phthalocyaninato-ligand; [m Br 4 TPP ] = tetrakis-meso-(3-bromophenyl)-porphyrinato-ligand) are synthesized for the first time with 43% and 36% yield. The applicability of the previously developed selective one-step synthetic approach for the preparation of the mentioned complexes is demonstrated and the limitations, determined by meta-substitution of meso-aryl-fragments, are revealed. The spectral features of the obtained complexes is determined by means of UV-vis and NMR spectroscopy. The hindered rotation of porphyrin meso-substituents in the obtained complexes and formation of statistical set of atropisomers are demonstrated.

    对称型[m Br 4 TPP ] Ln [(15 C 5)4 Pc ] Ln [m Br 4 TPP ] ( Ln -m TD ; Ln = La , Nd ;首次合成了[(15 C 5)4 Pc ] = 四(15-冠-5)-酞菁配体;[m Br 4 TPP ] = 四双介-(3-溴苯基)-卟啉配体),产率分别为 43% 和 36%。证明了之前开发的选择性一步合成法在制备上述复合物中的适用性,并揭示了由中芳基片段的元取代决定的局限性。通过紫外-可见光谱和核磁共振光谱确定了所获复合物的光谱特征。结果表明,卟啉中间取代基在所获得的复合物中旋转受阻,并形成了一组统计意义上的非对映异构体。
