Conclusions

  1. 1.

    The mechanism of the polarographic reduction of π-complexes of iron with the composition π-C5H5Fe(CO) (L)-σ-R [L=CO, P(C6H5)3 or P(OC6H5)3], containing Fe- C σ- bonds of various types, on a dropping mercury electrode was studied.

  2. 2.

    The influence of substiturnts in the p-position of the phenyl ring (R=C6H4-X) is described by aromatic polar substituent constants σp o, which is evidence of a weak polar influence of substituents upon the transition state of the electrochemical reaction studied.

  3. 3.

    The ease of reduction of the Fe-C σ-bond depends upon the stability of the carbanion formed and varies parallel with its basicity.
