Electrochemical oxidation and reduction of methylene-bridged complexes of manganese, cobalt, and rhodium
(The American Chemical Society: Organometallics, 1987-08)
The oxidation and reduction of a series of alkylidene-bridged dimetallic compounds containing Mn, Co, or Rh have been studied by electrochemical and spectroscopic techniques. Oxidation results in production of a cation ...
Unusual oxidative behavior of (.eta.5-C5R5)M(CO)2 (R = H, CH3; M = Rh, Co) complexes at mercury and platinum electrodes
(The American Chemical Society: Inorganic Chemistry, 1987-06-17)
The electrochemical oxidative behavior of a series of cyclopentadienyl and pentamethylcyclopentadienyl carbonyl complexes of rhodium and cobalt is described. The voltammetric, polarographic, and coulometric data from the ...
Fast charge-transfer reactions of binuclear complexes undergoing large changes in metal---metal bond lengths
(Elsevier: Journal of Electroanalytical Chemistry, 1987-05-08)
Heterogeneous electron-transfer rates have been measured for three binuclear complexes, Cp2Fe2(CO)2(μ-SMe)2, 1, Cp2Fe2(CO)2(μ-PPh2)2, 2, and Cp2Mo2(μ-SMe)4, 3. Dahl and co-workers had shown previously that the cations of ...
Interconversion of conjugated and nonconjugated polyolefin cobalt complexes in two oxidation states: an electrochemical and NMR study
(The American Chemical Society: Journal of the American Chemical Society, 1986-11-26)
The kinetics of interconversion between the conjugated (1,3) and nonconjugated (1,5) isomers of cyclooctatetraene (cot) complexes of CpCo [Cp = C5H5] 1 and *CpCo [*Cp = C5Me5] 2 have been studied. Dynamic NMR studies were ...
Radicals of C7-polyolefin cobalt complexes: electrochemistry, reaction routes, and structure of a resulting dimer
(The American Chemical Society: Organometallics, 1986-07)
The reduction and oxidation of several cyclopentadienyl (Cp) cobalt complexes with pi-bonded CTpolyolefin ligands have been studied by electrochemical methods. The cycloheptadienyl complex CpCo(n^5-C7H9)+ is reversibly ...
Heterogeneous electron-transfer kinetics for some multiply bonded dirhenium complexes

Standard electrochemical rate constants kexob have been measured for the two sequential one-electron oxidations of triply-bonded dirhenium(II) complexes Re2X4(PR3)4, where X = Cl or Br, and PR3 = a monodentate tertiary ...
Solvent effects on the kinetics of simple electrochemical reactions. Further examination of metal ethylenediamine and ammine redox couples.
(Elsevier: Journal of Electroanalytical Chemistry, 1985-09-10)
The dependence of the kinetics of Co(en)33+/2+ exchange (en=ethylenediamine) at mercury electrodes upon the nature of the solvent is discussed further by examining the preexponential factors, Acorr, as well as double-layer ...
Role of solvent reorganization dynamics in electron-transfer processes. Theory-experiment comparisons for electrochemical and homogeneous electron exchange involving metallocene redox couples
(The American Chemical Society: Journal of Physical Chemistry, 1985-06-20)
Electrochemical rate constants and activation parameters are reported for the electron exchange of five metallocene couples and bis(benzene)chromium(I/0) in eight solvents at mercury electrodes. The solvents (acetonitrile, ...
Double-layer effects on electrochemical kinetics in nonaqueous media. Dependence reactant charge for some metallocene redox couples.
(Elsevier: Journal of Electroanalytical Chemistry, 1985-05-10)
The effect of altering the double-layer composition on standard rate constants, kob, for metallocene and related redox couples has been examined at mercury electrodes in dimethylformamide and acetonitrile containing ...
