Research Abstract

Unsaturated compounds between the second row elements such as carbon and oxygen has played an important role in the function of organic compounds. In order to open the new chemistry of unsaturated compounds, we focused our attention on multiple-bond compounds between heavier elements such as silicon and phosphorus as novel functional materials. As a result, several numbers of novel unsaturated compounds between heavier elements have been successfully synthesized by utilizing kinetic stabilization and we have revealed their functions on the basis of element chemistry.
