Syntheses, characterizations, and stereoelectronic stabilization of organometallic electron reservoirs: the 19-electron d7 redox catalysts .eta.5-C5R5Fe-.eta.6-C6R'6
First 17−18−19-Electron Triads of Stable Isostructural Organometallic Complexes. The 17-Electron Complexes [Fe(C<sub>5</sub>R<sub>5</sub>)(arene)]<sup>2+</sup> (R = H or Me), a Novel Family of Strong Oxidants: Isolation, Characterization, Electronic Structure, and Redox Properties
The 18-electron complexes [MII(C5R5)(arene)]+ (M = Fe: R = H or Me, arene = C6H6-nMen (n = 0−6), C6H5NMe2, or C6Me5NH2; M = Ru: R = Me, arene = C6Me6) are oxidized to MIII complexes between 0.92 and 1.70 V vs [FeCp2] according to a single-electron process that is reversible in SO2 if at least one of the rings is permethylated. The dinuclear complex [FeII2(fulvalenyl)(C6Me6)][PF6]2 is oxidized in two

of the labile solvent ligand in these complexes by a phosphine results in the 17-electron (17e) cations [FeIIICp*(η2-dtc)(L)]+PF6-, L = PPh3 (7+PF6-) or η1-dppe (8+PF6-). The same reaction in the presence of the anionic ligands CN-, SCN-, and Cl- affords the corresponding neutral 17e FeIII complexes (respectively compounds 11, 13, and 14). All these 17e complexes were characterized by IR, ESR, and Mossbauer

Imidazolium salts with suitable substituents are readily deprotonated to stable NHC carbenes using the electron-reservoircomplex [FeICp(eta6-C6Me6)], 1, in the presence of air (via a superoxide radical anion acting as a base). Less stable NHC carbenes can be conveniently obtained from imidazolium salts using the neutral base [FeIICp(eta5-C6Me5CH2)] obtained from 1 and air.
Mono- and heterobimetallic triazolylferrocene and cobalticiniumcomplexes and triazolium derivatives were synthesized by click reactions between the ethynylmetallocenes and benzyl azide or (azidomethyl)ferrocene followed by methylation reactions, respectively. Cyclic voltammetry data shed light on the electron-withdrawing character of the 1,2,3-triazolyl and triazolium substituents of the metallocenes
