Self-promoted electron transfer from cobalt(II) porphyrin to p-fluoranil to produce a dimer radical anion-cobalt(III) porphyrin complex.
Self-promoted electron transfer from a cobalt(II) porphyrin [Co(II)OEP] to p-fluoranil (F4Q) occurs, exhibiting a second-order dependence of the electron-transfer rate with respect to the F4Q concentration due to the formation of a strong complex between the dimer radical anion [(F4Q)2*-] and the resulting Co(III)OEP+.
