| 研究開始時の研究の概要 |
In this research, we are planning to prepare first representatives of a new highly attractive class of organic compounds, pyramidanes C[C4R4], that have never been synthesized before. Such novel cluster compounds are of particular importance from both fundamental and applied points of view.
|
| 研究実績の概要 |
In this project we aim to synthesize a new class of clusters, pyramidanes, and study their reactivity. During the second year, we discovered unprecedented reactivity of pyramidanes towards organolithium reagents, forming Ge-anionic bicyclopentene derivatives, which can be functionalized to form cyclic and polycyclic compounds.

理由
The research plans of the second year of the project were realized, in accord with the original plans. Several pyramidanes were synthesized, and their specific reactivity was systematically studied. Particularly important was the interaction of pyramidanes with nucleophilic reagents, such as organolithium compounds, to form a series of unprecedented Ge-anionic bicyclo[2.1.0]pentene derivatives. Thus, during the second year, the project was proceeding smoothly with no troubles and in accord with the proposed plan.
|
| 今後の研究の推進方策 |
In the third year of the project, we are going to expand the range of novel pyramidanes, including all-carbon and all-silicon derivatives, applying different synthetic approaches to achieve these goals. All novel compounds will be fully structurally characterized and computationally studied, and their specific reactivity will be thoroughly studied.
