Outline of Final Research Achievements |
Synthesis of the hybrid molecules between polyacenes, which are linearly-fused polycyclic benzenoide aromatic compounds, and metallocenes, which are transition-metal-containing aromatic compounds, was examined. As a metallocene scaffold, ferrocene was chosen because of its chemical stability and easier handling, and the construction of acene moieties within the coordination-spheres of ferrocenes was examined. Introduction of two allylic substituents at the adjacent positions of a single Cp ligand in ferrocene, and treatment of the prepared ferrocene derivative with the Grubbs catalyst facilitated the ring-closing metathesis reaction to give the corresponding dihydroindenyl compound in nearly quantitative yield. Application of a similar reaction to decaallylferrocene gave single-bridged bis(tetrahydrofluorenyl)iron(II) species in high yield via five-fold ring-closing metathesis within a single molecule.
