Electrochemical oxidation of organic,organometallic, and coordination compounds. Polarization effect in radical cations

Half-wave potentials of electrochemical oxidation of 24 reaction series X-B-R_C depend on the inductive, resonance, and polarization effects of substituents X. The polarization effect was not taken into account previously. In X-B-R_C ^·+ radical cations, the contribution of the polarization effect increases with decreasing size of bridge B linking X with the reaction center R_C and can reach 30%.
