| 英文摘要 | high-valent cobalt-oxo intermediates are proposed as reactive intermediates in a number of cobalt-complex-mediated oxidation reactions. herein we report the spectroscopic capture of low-spin (s=1/2) co-iv-oxo species in the presence of redox-inactive metal ions, such as sc3+, ce3+, y3+, and zn2+, and the investigation of their reactivity in c-h bond activation and sulfoxidation reactions. theoretical calculations predict that the binding of lewis acidic metal ions to the cobaltoxo core increases the electrophilicity of the oxygen atom, resulting in the redox tautomerism of a highly unstable [(taml)co-iii(o-center dot)](2-) species to a more stable [(taml)co-iv(o)(mn+)] core. the present report supports the proposed role of the redox-inactive metal ions in facilitating the formation of high-valent metal-oxo cores as a necessary step for oxygen evolution in chemistry and biology. |
