A novel [FeFe]-hydrogenase biomimetic catalyst [(μ-dmedt)Fe₂(CO)₅](μ-DPPF-O) (1) was prepared by CO-substitution in the (μ-dmedt)[Fe₂(CO)₆] complex with DPPF in THF. Confirmation of the catalyst structure was determined by FTIR, ¹H NMR, ¹³C NMR, ³¹P NMR and single crystal X-ray diffraction. Complex 1 exhibited better catalytic reactivity for phenol hydroxylation than the all-carbonyl complex (μ-dmedt)[Fe₂(CO)₆]. The dihydroxybenzene selectivity of 94.0% and phenol conversion of 42.9% were obtained under the optimal reaction conditions. The relationships between electron density of the FeFe bond and the catalytic activity of these complexes were revealed, which showed that the more electron rich the FeFe bond is, the better catalytic hydroxylation activity was achieved.

通过在（μ-dmedt）[Fe ₂（CO ）中进行CO取代制备了一种新型的[FeFe]-氢化酶仿生催化剂[（μ-dmedt）Fe ₂（CO）₅ ]（μ-DPPF-O）（1）。）₆ ]与DPPF在THF中的络合物。通过FTIR，¹ H NMR，¹³ C NMR，³¹ P NMR和单晶X射线衍射确定催化剂结构。复杂1表现出更好的催化活性为苯酚羟基化比全-羰基络合物（μ-dmedt）的[Fe ₂（CO）₆]。在最佳反应条件下，二羟基苯的选择性为94.0％，苯酚的转化率为42.9％。揭示了Fe- Fe键的电子密度与这些配合物的催化活性之间的关系，表明Fe- Fe键的电子越富集，催化羟基化活性就越好。
