ELECTRON TRANSFER REDUCTION OF FLUOROFULLERENES,C_(60)F_(36),AND C_(60)F_(18)

摘要

Fluorofullerenes,C_(60)F_(36) and C_(60)F_(18),have unique structures identified by X-ray analyses,which have revealed the presence of three/four and one pi-delocalized benzenoid rings,respectively.These fullerenes are strong oxidants as compared to C_(60) due to strongly electron-deficient fluorines.Halogenated fullerenes such as C_(60)C1_6,C_(60)Br_6 and C_(60)Br_8 are known to form charge-transfer complexes with organic donors and it is anticipated that increased electron withdrawal by the halogenated cage would increase electron-transfer reduction.We have recently reported electron transfer reduction mechanism and one-electron reduction potential of C_(60)F_(18).However,the electron transfer reactivity of the stronger oxidant,C_(60)F_(36),has yet to be reported.
