Outline of Final Research Achievements |
The C-C single bond length of 1.791(3) angstrom has been considered the longest value among neutral organic compounds. Expandability/fissionability of such a long bond in crystals plays an important role for construction of response system. Toward the realization of higher-order response system, further longer C-C bond could work efficiently due to large expandability of the weakened bond. Therefore, we have designed a compound with a bond length beyond 1.8 angstrom. In this study, a highly strained hydrocarbon, which has the longest C-C single bond with a bond length of 1.806(2) angstrom, has been synthesized based on the intramolecular "core-shell strategy": the weak C-C bond (core) is protected by the shape-persistent sp2 carbon framework (shell). We proposed to term the C-C bond with a bond length of 1.8-2.0 angstrom "hyper covalent bond".
