摘要：

The 19-electron complexes [Fe-I(n(5) -C5R5)(n(6) -arene)] (R = H, arene = C6Me6, 1,3,5-tBu(3)C(6)H(3); R = Me, arene = C6Me6, C6Et5H) are thermally stable and serve as strong single-electron reductant in a variety of stoichiometric and catalytic electron-transfer processes that are detailed in this review (prototype: [Fe-I(n5 -C5H5)(n(6) -C6Me6)]). They are electron-reservoirs because their redox potential is very negative and they form a redox system for which both redox forms are stable. In this sense, they are Green redox reagents, since the oxidized form is recovered after use and is even frequently catalytically used. Symmetrically, the 17-electron complex [Fe-III (n(5)-C5R5)(n(6) -C6Me6)][SbCl6](2), the strongest organometallic single-electron oxidant with a redox potential 1 V more positive than that of its isoelectronic ferrocenium analog, is a reservoir of electron hole.
