    摘要:
    本文描述了一种获得芳基取代脂肪族羧酸的基本纯对映体的方法。该方法首先利用手性分辨、对映异构体结晶或不对称合成工艺获得芳基取代脂肪族羧酸的对映体富集混合物。将这种富集混合物与碱反应,产生具有以下特性的盐:1)至少具有一个共晶点;2)具有不在共晶点的组成;3)共晶组成比芳基取代羧酸的共晶组成更接近于消旋组成。分离出基本纯的对映盐,留下溶剂和富集了另一对映体的芳基取代脂肪族羧酸母液。

    Model of short-range order in a concentrated lanthanum trichloride aqueous solution from x-ray diffraction studies
    摘要:
    A concentrated aqueous solution of LaCl3 has been investigated by the X-ray diffraction method. The main features of the pair function are consistent with the presence of the [La(H2O)9Cl2]+ complex additionally hydrated in the second sphere. The outer-sphere Cl- ions are hydrogen bonded to the inner-sphere water molecules. The La3+-Cl- distance points either to a trigonal orientation of inner-sphere water molecules and the hydrogen bond angle of 170-degrees or to the tilt angle of 30-degrees and a linear hydrogen bond.

    The effectiveness of salts of [LnIIIW10O36]9− (Ln=Y, La, Ce, Pr, Sm, Eu, Gd, Dy, Er, Lu) and [MIVW10O36]8− (M=Ce, Th) as catalysts with H2O2 for alcohol oxidations and alkene epoxidations has been studied. It appears that catalysis arises from the polyperoxotungstates formed from H2O2. The X-ray crystal structure of the title complex shows that in the [ThW10O36]8− anion the thorium has square antiprismatic

    The synthesis of the phenyl anchored podand H4L1 fitted with four 3-carboxylate pyrazole arms and programmed for intermolecular interactions is reported, and its protonation constants are determined. Interaction with Ln3+ ions (Ln = La, Eu, Lu) in dilute aqueous solutions leads to complexes with 1:1 and 1:2 metal−ligand stoichiometry. The stability constants are in the range log β110 = 12.7−13.5 and
