| Outline of Final Research Achievements |
Silicon-containing cyclic 4npi-electron systems were constructed and their characteristics were revealed. We successfully synthesized benzodisilacyclobutadienes, which exhibited a significant contribution of a 1,2-disilacyclobutadiene resonance structure. We also synthesized naphtho- and anthrodisilacyclobutadienes and compared their structure and (anti)aromaticity by various spectroscopies, structural analysis, and theoretical studies.
An isolable 1H-phosphadisilirene was obtained as red-purple crystalline solid. In obtained 1H-phosphadisilirene, significant orbital interactions between disilene moiety and phosphorus atoms in the three-membered ring was indicated by UV-vis spectrum and theoretical studies.
