| Outline of Final Research Achievements |
In this research, we investigated to synthesize new metal compounds bearing a low-valent silicon- and germanium-based ligand as active metal complexes that can mediate new reactions. Indeed, we succeeded to isolate several such complexes and found new types of reactions that have not been observed before. One of the most notable achievements is that a metathesis-like reaction was found to occur in the reaction of a silylyne complex with arylaldehydes through double [2+2] cycloaddition followed by fragmentation of the resulting four-membered-ring complexes.
