The homogeneous one- or two-electron oxidation of the Co(III) σ-bonded complexes was accomplished using [Fe(phen)3]3+ (phen = 1,10-phenanthroline) as an oxidant. The products of the initial oxidation as well as that of the subsequent R group migration from (TPP)Co(R) or (TPP)Co(R)(L) to give the N-aryl or N-alkyl Co(II) porphyrins were characterized by ESR and UV−vis spectroscopies, while the rates of migration were determined using stopped flow kinetics. The rate constants of R group migration from the metal to nitrogen in [(TPP)Co(R)]+ were found to vary by 6 orders of magnitude upon going from (TPP)Co(Ph) (1.3 × 10-3 s-1) to (TPP)Co(Bu) (1.2 × 103 s-1) at 298 K in acetonitrile, but no significant differences were observed between E1/2 for the f..."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388845762950659","@type":"Researcher","foaf:name":[{"@value":"Shunichi Fukuzumi"}],"jpcoar:affiliationName":[{"@value":"Contribution from the Department of Applied Chemistry, Faculty of Engineering, Osaka University, Osaka 565-0871, Japan, and Department of Chemistry, University of Houston, Houston, Texas 77204-5641"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845762950658","@type":"Researcher","foaf:name":[{"@value":"Kenichi Miyamoto"}],"jpcoar:affiliationName":[{"@value":"Contribution from the Department of Applied Chemistry, Faculty of Engineering, Osaka University, Osaka 565-0871, Japan, and Department of Chemistry, University of Houston, Houston, Texas 77204-5641"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845762950660","@type":"Researcher","foaf:name":[{"@value":"Tomoyoshi Suenobu"}],"jpcoar:affiliationName":[{"@value":"Contribution from the Department of Applied Chemistry, Faculty of Engineering, Osaka University, Osaka 565-0871, Japan, and Department of Chemistry, University of Houston, Houston, Texas 77204-5641"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845762950656","@type":"Researcher","foaf:name":[{"@value":"Eric Van Caemelbecke"}],"jpcoar:affiliationName":[{"@value":"Contribution from the Department of Applied Chemistry, Faculty of Engineering, Osaka University, Osaka 565-0871, Japan, and Department of Chemistry, University of Houston, Houston, Texas 77204-5641"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845762950657","@type":"Researcher","foaf:name":[{"@value":"Karl M.
