Does one-electron transfer to nickel(II) porphyrins involve the metal or the porphyrin

Nickel(1) complexes can be reversibly produced by one-electron electrochemical reduction of nickel(II) porphyrins within the time scale of cyclic voltammetry as well as thin-layer and conventional cell electrolysis in solvents such as dimethylformamide and benzonitrile. UV-vis and ESR spectroscopies indicate the formation of a nickel(I) complex rather than the anion radical of the nickel(II) porphyrin. ESR data suggest an out-of-plane displacement of the nickel(I) ion caused by the insufficient size of the hole offered by the porphyrin ligand. 23 refs., 6 figs., 4 tabs..
