Alkylated porphyrins, redox potentials

The redox potential for the (por)Com/ /(porT)Com/ couple is more negative than the corresponding (por)Fe 1/ /(porT)Fe111/ couple (Table 13.8). In contrast to alkyl-iron porphyrins, (po Co111/ is not reduced by the (por)Co anion. Instead, it is reduced to (porT)CoUI7 anion by a more negative scan (Em, -1.17 to -1.36 V).
