Near-UV excitation of non-heme Fe[double bond, length as m-dash]O complexes results in light intensity dependent increase in reaction rates for the oxidation of C-H bonds even at low temperature (-30 °C). The enhancement of activity is ascribed to the ligand-to-[Fe[double bond, length as m-dash]O] charge transfer character of the near-UV bands to generate a highly reactive [(L) Fe-O*] species. The enhancement is not observed with visible/NIR excitation of the d-d absorption bands.
非血红素铁-氧（Fe=O）配合物的近紫外光激发即使在低温（-30°C）下也会导致C-H键氧化反应速率随光强度增加。活性的增强归因于近紫外波段的配体到[Fe=O]电荷转移特性，从而产生高活性的[(L)Fe-O*]物种。在d-d吸收带的可见光/近红外光激发下未观察到这种增强。
