Following the research proposal, these significant results described below were accomplished. First in the establishment of basic methods for the syntheses of functional materials: (1) Cyclic silanols those serve as the versatile starting compounds for various siloxane materials were easily accessed in high yields, (2) Investigation of substituents made it possible to afford the products with single stereo structure. For innovational core compounds synthesis with reactive groups, (1) cage octasilsesquioxanes with eight reactive substituents (octopus), (2) laddersiloxanes with two reactive groups on the both ends were synthesized. In addition, cage hexasilsesquioxanes with two different substituents, which was not included in the proposal documents, was also obtained by a facile method. In summary, several versatile new synthetic methods and potential functional silicon materials were obtained in this project.

根据研究建议，取得了下述重要成果。首先，在功能材料合成的基本方法的建立：（1）环硅醇，作为各种硅氧烷材料的通用起始化合物，容易地以高产率获得。（2）取代基的研究使得有可能提供具有单一立体结构的产物。在含反应性基团的新型核心化合物的合成方面，合成了（1）含八个反应性取代基的笼型八倍半硅氧烷（章鱼），（2）两端含两个反应性基团的梯型硅氧烷。此外，还通过简单的方法得到了建议文件中未包括的具有两个不同取代基的笼形六倍半硅氧烷。综上所述，本项目获得了几种新的合成方法和潜在的功能硅材料。
