  镍卟啉的单电子氧化：结构和介质对卟啉镍（III）或卟啉镍（II）形成的影响

  摘要：

  The oxidation of several nickel(II) porphyrins by various radicals has been studied by pulse radiolysis in different media (Cl2.- and Br2.- in aqueous systems, Br atoms in organic solvents, and peroxyl radicals in organic and aqueous/organic systems). Photochemical oxidation was also examined in some cases. The absorption spectrum of the oxidation product was monitored within several microseconds after the pulse. Two types of differential spectra were observed, a broad absorption at 640-700 nm ascribed to the pi-radical cation, or a sharp absorption at 560-580 nm ascribed to nickel(III) porphyrin. Ni(II)TPP (tetraphenylporphyrin) in several organic solvents, protic and aprotic, was oxidized to Ni(III)TPP. The addition of 10% water as cosolvent or 0.1 M of electrolyte changed the route of oxidation to give the radical cation Ni(II)TPP.+. On the other hand, Ni(II)TSPP (tetrakis(4-sulfonatophenyl)porphyrin), which has four negative charges, was oxidized on the porphyrin ligand by all the radicals examined, in water and in several organic solvents. Ni(II) bis(N-methyl-4-pyridyl)diphenylporphyrin, with a charge of +2, and Ni(II) tris(4-sulfonatophenyl)(N-methyl-4-pyridyl)porphyrin, with an overall charge of -2, were oxidized on the ligand in aqueous solution but on the metal in organic solvents. These and other results led to the conclusion that most radicals react with Ni(II)P by an inner-sphere mechanism to bind onto the metal and give the Ni(III)P form. However, when the porphyrin is sufficiently charged to repel the axially bound anion, and/or when the medium enhances the separation of this anion from the metal, the result is oxidation of the porphyrin pi-system. In all cases, however, the one-electron-oxidation products, whether Ni(II)P.+ or Ni(III)P, decay to yield two-electron ring oxidation products.
