2023-10-16 Tracking an FeV(O) Intermediate for Water Oxidation in Water doi:10.57760/sciencedb.10784 en High-valent iron-oxo species are appealing in conducting O–O bond formation for water oxidation reaction. However, their high reactivity poses a great challenge to dissection of their chemical transformations. Herein, we introduce an electron-rich and oxidation-resistant ligand, 2-[(2,2’-bipyridin)-6-yl]propan-2-ol to stabilize such fleeting intermediates. Advanced spectroscopies and electrochemical studies demonstrate a high-valent FeV(O) species formation in water. Combining kinetic and oxygen isotope labelling experiments and organic reactions indicates that the FeV(O) species is responsible for O–O bond formation via water nucleophilic attack under the real catalytic water oxidation condition. water oxidation; iron-based complex; homogenous catalysis 魏相竹 PUBLIC https://creativecommons.org/publicdomain/zero/1.0/ dataset Science Data Bank
