Outline of Final Research Achievements

The purpose of this study was to create new macrocyclic multinuclear complexes with rigid frameworks that can serve as reaction fields for highly selective and active reactions. As a result, interesting results regarding the following topics have been obtained. (1) Site-selective bridging of macrocyclic hexanuclear palladium complexes by linear bidentate ligands. (2) Reactions of cyclic oligomers of pyridylbenzoxazole (pbo) and its multinuclear complexes. (3) Synthesis of cyclic oligomers of sap units from a bifunctional monomer with biphenol moiety and the formation of multinuclear complexes.

Academic Significance and Societal Importance of the Research Achievements

数ある反応部位の中から、特定の部位を選択的に変換する合成法の開発は、望みの化合物を効率的に合成するための重要課題である。また、選択的かつ高効率な反応のためには、基質の配向および活性種の相対配置を制御する必要がある。剛直な骨格をもつ新たな大環状多核錯体の創製に成功した本研究は、基質や小分子を結合して活性種を生成して反応を促進する配位サイトを、一定間隔で配置するための新たな方法論を提供した。この成果は、錯体化学のみならず有機化学・薬学など幅広い学術・産業分野に波及効果をもたらす。
