- 中文摘要: The physical properties of mixed-valence 1,3-diferrocenyl-propan-1-one (1) are reported. The Mossbauer spectrum of mixed-valence cation 1 at 300K shows two doublets, one for an Fe/sup II/ metallocene(.DELTA.E/sub Q/=2.192mm s/sup -1/) and the other for an Fe/sup III/ metallocene (.DELTA.E/sub Q/=0.179mm s/sup -1/). Thus, the thermal electron-transfer rate in 1 is less than the time scale of the Mossbauter technique(ca. 10/sup 7/s/sup -1/). Furthermore, the NMR, electrochemical, IR, and near-IR data conclusively indicate that there is no significant interaction between the two ferrocenyl moieties.
