| Outline of Final Research Achievements |
We have successfully synthesized a series of neutral two-coordinate radicals of heavy group-15 elements, which enable us to compare their structures and reactivity. Novel platinum and iron complexes ligated by the phosphine-centered radical were also synthesized and we found that the phosphinyl radical works as a stronger pi acceptor compared to trialkylphosphine and stabilizes the low-coordinate metal radical center. We also developed novel photochemical transformation reactions of azulenes in the presence of a dialkylsilylene. A novel silylene with balancing thermal stability and reactivity was synthesized. Using this new silylene, we disclosed unprecedented intermolecular C-H insertion reactions of a silylene as well as dehydroaromatization reactions.
