|Abstract||Polarog. half-wave potentials for 2 redn. steps of 49 cyclopentadienyliron complexes of substituted arenes or heterocycles in DMF were detd. A fast cyclic voltammetry (10-40 V/s) was used to study the electron transfer kinetics of some of these complexes. After correction for the double layer effects, the rate consts. of all the complexes studied show that the transfer of electrons in the 2nd redn. step occurs significantly faster than in the 1st one. This was interpreted as a result of greater delocalization of electrons in the 20-electron complexes of Fe compared to the 19-electron complexes. [on SciFinder(R)]|
