quasi-reversible Co(i)/Co(ii) redox couple at ~-1.1 V and an irreversible Co(ii)/Co(iii) couple at ~1.3 V vs. Ag/AgCl in DMF-0.1 M [Bun4N](ClO4). co(iii) 107-114 mitochondrially encoded cytochrome c oxidase II Homo sapiens 100-106 32814135-5 2021 Based on the characterization results, the sulfate radicals and hydroxyl radicals were considered to be the main free radicals which were involved into the circulation of Co(II)-Co(III)-Co(II) as well as the oxidation of Fe(II), which was responsible for the remarkable catalytic efficiency. co(iii) 178-185 mitochondrially encoded cytochrome c oxidase II Homo sapiens 171-177 32814135-5 2021 Based on the characterization results, the sulfate radicals and hydroxyl radicals were considered to be the main free radicals which were involved into the circulation of Co(II)-Co(III)-Co(II) as well as the oxidation of Fe(II), which was responsible for the remarkable catalytic efficiency. co(iii) 178-185 mitochondrially encoded cytochrome c oxidase II Homo sapiens 186-192 30962670-6 2019 Monitoring the addition of HBPin to [(iPrPNP)Co(N2)]+ provided evidence for a transient Co(III) oxidative addition product that likely undergoes comproportionation with the cobalt(I) starting material to generate the observed Co(II) products. co(iii) 88-95 mitochondrially encoded cytochrome c oxidase II Homo sapiens 226-232
