pairs of electronically tuned oxoiron(IV) geometrical isomers is described, as a model for the “ferryl flip” observed in non-heme enzymes. The position of the oxo ligand in the coordination sphere of the iron center has a strong impact on the hydrogen-atom transfer (HAT) activity of the oxoiron(IV) compounds, while electronic effects do not play a significant role in HAT reactions.
描述了成对的电子调谐氧铁 (IV) 几何异构体的异构化,作为在非血红素酶中观察到的“铁基翻转”的模型。氧代配体在铁中心配位层中的位置对氧代铁 (IV) 化合物的氢原子转移 (HAT) 活性有很大影响,而电子效应在 HAT 反应中并不起重要作用。
