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
(Elsevier: Journal of Electroanalytical Chemistry, 1985-12-10)
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 ...
Electrochemical redox behaviour of the hexakis-(aryl isocyanide) complexes of molybdenum(0) and tungsten(0)
(Elsevier: Inorganica Chimica Acta, 1985-02-15)
Les complexes hexakis(phénylisocyano), Mo(CNPh)[6] et W(CNPh)[6], dans le mélange d'hexafluorophosphate de tétrabutylammonium 0,2 M et de dichlorométhane, présentent une vague d'oxydation réversible à un électron à E[1/2]≃−0,2 ...
Influence of solvent reorientation dynamics upon the kinetics of some electron-exchange reactions
(Elsevier: Chemical Physics Letters, 1985-01-11)
The role of solvent reorientation dynamics is explored for outer-sphere electron transfer by examining the solvent-dependent rates for electrochemical exchange of selected organometallic redox couples. The observations are ...
Reliability of standard rate constants for rapid electrochemical reactions
(The American Chemical Society: Analytical Chemistry, 1984-07)
A method is outlined for testing the reliability of standard rate constants, k^s, for rapid electrode reactions evaluated by using electrochemical perturbation techniques. This entails monitoring the response of the apparent ...
