| Outline of Final Research Achievements |
Unsaturated compounds of main group elements with a highly polarized structure such as stannanone and tetrastannacyclobutadiene have been synthesized by taking advantage of the steric effects of the fused-ring bulky Rind groups (Rind = 1,1,3,3,5,5,7,7-octa-R-substituted s-hydrindacen-4-ly). The molecular structures and chemical bonding of the resulting unsaturated compounds have been elucidated by the experimental and theoretical studies. We have also examined the reactivity of the new unsaturated compounds of main group elements. Especially, we have investigated the oxidation reactions of the heavy cyclobutadienes, tetragermacyclobutadiene and tetrastannacyclobutadiene.
