Outline of Final Research Achievements

We have established methods to synthesize monovalent group 9 elemnt dithiolate complexes that can be handled in air, and have achieved structural determination and theoretical characterization of these art complexes. Furthermore, we have developed molecular transformation reaction via the cleavage of less reactive covalent bonds by the art complexes. In the hydrosilylation of electron-deficient alkynes catalyzed by the rhodium ate complex, the reaction proceeded with different selectivity than other rhodium complexes. On the other hand, the iridium ate complex showed high catalytic activity in the synthesis of disiloxanes.

Academic Significance and Societal Importance of the Research Achievements

1価9族元素アート錯体の合成および触媒反応への展開は極めて限られており、これらのアート錯体に特有の触媒機能が見出された例はこれまでにない。本研究において、特にロジウムジチオラート錯体が他のロジウム錯体とは異なる触媒機能を有することを実証したことは、アート錯体触媒を用いる新たな分子変換反応の方法論を提案するものであり、学術的意義は大きい。
