Abstract
The key intermediate of a bioinspired iron catalyst for selective hydrocarbon oxidation based on hydrogen peroxide and an iron complex with a tetradentate aminopyridine ligand was trapped by EPR. On the basis of EPR and reactivity data this intermediate is tentatively proposed to be an oxoiron(V) complex.
摘要
基于过氧化氢和具有四齿氨基吡啶配体的铁配合物的用于选择性烃氧化的仿生铁催化剂的关键中间体被电子顺磁共振（EPR）捕获。基于电子顺磁共振和反应性数据，初步推测该中间体为氧代铁（V）配合物。
