“…Reversible monoelectronic reduction of these cationic complexes was reported using cyclic voltammetry 18. The benzene and polymethylbenzene derivatives can be reduced by sodium/mercury in tetrahydrofuran to yield unstable 19‐electron complexes that dimerize through the arene ligand in pentane,19 or catalytically disproportionate in tetrahydrofuran under the influence of a salt at sub‐ambient temperatures 20. However, for the hexamethylbenzene ligand, the dimerization was found to be sterically inhibited, the 19‐electron complex [CpFe I (η 6 ‐C 6 Me 6 )], 1 , was thermally stable at up to 100 °C, and its X‐ray crystal structure was solved 21.…”

“…The parent complex [Fe 15 whose potential is 0.5 V more negative than that of cobaltocene can be used at 0 C in solution, but its isolation and storage in the solid state requires to work at À10 C. The use of the complex [Fe I ( 5 -C 5 H 5 )( 6 -C 6 Me 6 )] is routine and standard, 62 because it does not decompose below 100 C, and its synthesis is facile (under rigorously inert atmosphere). It can be stored for a long time and its multiple uses have been described in this review.…”

“…All the monocationic 18e complexes can be preparatively reduced to the forest-green 19-electron neutral species that rapidly decomposes or dimerizes below room temperature. 15 Reduction must be carried out at low temperature using Na/ Hg or LiAlH 4 in order to study the Fe I species in solution. The benzene complex itself is modesty stable at 0 C and spontaneously dimerizes at room temperature, which was disclosed by Nesmeyanov's group.…”

The 19-electron complexes [FeI(η5-C5R5)(η6-arene)] (R=H, arene = C6Me6, 1,3,5-tBu3C6H3; 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: [FeI(η5-C5H5)(η6-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 [FeIII(η5-C5R5)(η6-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.

“…The catalytic reduction of C 0 2 has recently attracted considerable attention1 in view of the possibilities of using this abundant, low-cost source of chemicals.2 The thermodynamic potential E" of the redox system C02/C02-' is difficult to determine because of the high rates of reactions of C02-', but it can be calculated as -2.21 V V.T. standard 6 or Me ( 2 (3). The 19 electron complex (2) rapidly reacts with C02 in tetrahydrofuran (THF) under ambient conditions (20 "C, 1 atm) or at 0°C to give cleanly a yellow precipitate of (2+), 4…”
