Lack of electronic coupling despite half-wave potential splittings in ferrocenylvinyl-substituted [2.2]-paracyclophanes

Pseudo-para bis(ferrocenylvinyl)-[2.2]-paracyclophane 2 and its constitutional isomer 3 have been prepared and investigated with respect to their electrochemical and UV/Vis/NIR spectroelectrochemical properties. Cyclic and Square Wave voltammetric measurements show two consecutive one-electron oxidations with a modest redox splitting of 60 and 84 mV, respectively, for the individual Fc/Fc+ couples. In spite of the redox splitting, radical cations 2+ and 3+ constitute class I mixed-valent systems with no detectable electronic coupling between the individual redox sites. The results are thus very similar to those for the pseudo-ortho isomer 1 +, which was previously reported (J. Organomet. Chem. 2012, 717, 14) but erroneously assigned the pseudo-para structure.

The d4/d3 redox pairs [MX(CO)(eta-RCCR)Tp?] z (z = 0 and 1): Structural consequences of electron transfer and implications for the inverse halide order

The d4 halide complexes [MX(CO)(eta-RCCR)Tp?] {X = F, Cl, Br or I; R = Me or Ph; M = Mo or W; Tp? = hydrotris(3,5- dimethylpyrazolyl)borate} undergo one-electron oxidation to the d3 monocations [MX(CO)(eta-RCCR)Tp?]+, isolable for M = W, R = Me. X-Ray structural studies on the redox pairs [WX(CO)(eta-MeCCMe)Tp?] z (X = Cl and Br, z = 0 and 1), the ESR spectra of the cations [WX(CO)(eta-RCCR)Tp?]+ (X = F, Cl, Br or I; R = Me or Ph), and DFT calculations on [WX(CO)(eta-MeCCMe)Tp?]z (X = F, Cl, Br and I; z = 0 and 1) are consistent with electron removal from a HOMO (of the d4 complexes) which is pi-antibonding with respect to the W-X bond, pi-bonding with respect to the W-C(O) bond, and delta-bonding with respect to the W-Calkyne bonds. The dependence of both oxidation potential and nu(CO) for [MX(CO)(eta-RCCR)Tp?] shows an inverse halide order which is consistent with an ionic component to the M-X bond; the small size of fluorine and its closeness to the metal centre leads to the highest energy HOMO and the lowest oxidation potential. In the cations [MX(CO)(eta-RCCR)Tp?] + electronegativity effects become more important, leading to a conventional order for Cl, Br and I. However, high M-F pi-donation is still facilitated by the short M-F distance. The Royal Society of Chemistry.

Ferrocene end-capped palladium(II) and platinum(II) complexes with thiophene spacers

A series of heterobimetallics containing ferrocene and Pd(II) or Pt(II) have been synthesized by oxidative addition of ferrocene-substituted halothiophenes with zerovalent palladium or platinum precursors. The stable solids were thoroughly characterized by elemental analysis, NMR, UV-vis spectroscopy, and cyclic voltammetry. The rich redox chemistry of the complexes depends on the conjugation length that separates the two metal sites. The crystal structure of a platinum sigma-thienyl complex, (C5H5)Fe(C5H4CH=CH-th-Pt(PPh 3)2(Br)) (th = 2,5-disubstituted thiophene) has been determined.

Tentative structural conclusions are drawn for the reaction products based upon analysis, electrical conductance, magnetic moment and spectral (UV-Visible, IR, 1H NMR and 13C NMR) data. FAB mass spectra of complexes were also recorded to confirm the binuclear structures. Studies were conducted to assess the growth inhibiting potential of the ligands and complexes against various fungal and bacterial strains.

Development of a miniaturized injection cell for online electrochemistry?capillary electrophoresis?mass spectrometry

Abstract: The elucidation of oxidation or reduction pathways is important for the electrochemical characterization of compounds of interest. In this context, hyphenation of electrochemistry and mass spectrometry is frequently applied to identify products of electrochemical reactions. In this contribution, the development of a novel miniaturized injection cell for online electrochemistry?capillary electrophoresis?mass spectrometry (EC?CE?MS) is presented. It is based on disposable thin-film electrodes, which allow for high flexibility and fast replacement of electrode materials. Thus, high costs and time-consuming maintenance procedures can be avoided, which makes this approach interesting for routine applications. The cell was designed to be suitable for investigations in aqueous and particularly non-aqueous solutions making it a universal tool for a broad range of analytical problems. EC?CE?MS measurements of different ferrocene derivatives in non-aqueous solutions were carried out to characterize the cell. Oxidation products of ferrocene and ferrocenemethanol were electrochemically generated and could be separated from the decamethylferricenium cation. The importance of fast CE?MS analysis of instable oxidation products was demonstrated by evaluating the signal of the ferriceniummethanol cation depending on the time gap between electrochemical generation and detection. Graphical abstract: [Figure not available: see fulltext.].
