Outline of Final Research Achievements

We investigated new types of functional molecules and synthesized many “stimuli-responsive” metal complexes that have a variety of multiple bonds between silicon or germanium and transition metals. Spectroscopical properties and X-ray crystal structures of the products were clarified. The study of their reactivity resulted in finding several new types of reactions. Especially, through the investigation using triple bonded complexes, we obtained many kinds of new [2+2] cycloaddition products, ketone-coupling products, and also found the metathesis-like fragmentation reaction, which is the first example of this type of reaction in the silicon system and is a significant result from the viewpoint of the reaction chemistry.
