Chemical implications of the two-electron redox chemistry observed for Fe(3)(CO)(9)(mu(3)-PMn(CO)(2)Cp)(2): Reductive coupling in multielectron chemical transformations

he two-electron redox chemistry observed for the triiron cluster ;Bidentate phosphine-substituted clusters ;A method was developed to determine the protonation rate of cluster dianions by cyclic voltammetric analysis in the pseudo first-order kinetic regime. Corrections for slow heterogeneous electron transfer are shown to be necessary for accurate analysis of the protonation rates. Data collected for the analyte only (no added acid) were used to obtain a correction factor for each scan rate. Cluster ;Crystallographic results for...
