| Outline of Final Research Achievements |
Various methods for the direct synthesis of heavy phenyl anions without using bulky substituents were investigated, but it was not possible to develop a completely protection-group-free synthetic route due to the difficulty in handling intermediates. However, optimization of the synthetic route for stable heavy benzenes protected with a bulky substituent as precursors enabled us to synthesize heavy phenyl anions in a large scale, which led to the development of new single Ge atom transport reactions reflecting their unique reactivity and other very interesting applications from the viewpoints of element chemistry.

| Academic Significance and Societal Importance of the Research Achievements |
GeおよびSnを含む重いフェニルアニオン種の合成と応用の成果を踏まえ、Si類縁体の合成にも挑戦し、Tbt基置換の系ではSiの元素特性を反映した分子内脱プロトン化を経たジアニオン種の生成を、 また分子内プロトン源のないEind基置換の系では目的のシラベンゼニルアニオンの発生を示唆する結果を得た。これらの14族元素を俯瞰する系統的研究は、元素特性の体系化と活用という観点から学術的に重要である。
