(1) Several bi- and tridentate ligands had been prepared, and in addition to the monodentate ligand, tri-n-octylphosphine oxide (TOPO), they were applied to the synergistic extraction of alkaline earth metals and lanthanide metals. Bis (diphenylphosphinyl) methane (BDPPM) was found to be the most powerful adduct forming ligand. The compositions of the extracted species were confirmed by a graphical method. The extraction constants were calculated on the basis of the composition of the extracted species and elucidated in terms of the molecular structure.(2) Novel 4-acyl-5-pyrazolones having the crown ether moiety as the intramolecular synergist have been synthesized and the solvent extraction of various metal ions are examined. It is expected that the crown ether moiety could behave as the intramolecular synergist and that the selectivity could be governed by the acylpyrazolone and the crown ether parts. These ligands are powerful and selective extracting reagents for alkali, alkaline earth and divalent transition metal ions, and the selectivity is quite unique depending on the intramolecular synergist.

(1)合成了几种二齿和三齿配体，并将它们与单齿配体三辛基氧化膦（TOPO）一起应用于碱土金属和镧系金属的协同萃取。双（二苯基膦基）甲烷（BDPPM）被认为是最强大的加合物形成配体。通过图解法确认了提取物的组成。提取常数的基础上计算的提取物的组成和阐明的分子结构。(2)合成了一种新型的含冠醚结构的4-酰基-5-吡唑啉酮类化合物，并研究了其对金属离子的萃取性能。预计冠醚部分可以表现为分子内取代基，并且选择性可以由酰基吡唑啉酮和冠醚部分控制。这些配体对碱金属、碱土金属和二价过渡金属离子是强有力的选择性萃取剂，并且选择性取决于分子内的电子结构。
