Developing new catalysts for highly efficient and selective oxidation of saturated C–H bonds is significant due to their thermodynamic strength. Via incorporation of PW₁₂O₄₀³^–, pyridine-2,5-dicarboxylic acids (pydc), and Fe(III) ions into one framework, a new polyoxometalate-based metal–organic framework, [HFe₄O₂(H₂O)₄(pydc)₃PW₁₂O₄₀]·10.5H₂O (FeW–PYDC), was successfully prepared by a hydrothermal method. Interestingly, FeW–PYDC features a three-dimensional porous structure with {Fe₄O₂} interconnecting with PW₁₂O₄₀³^– units. FeW–PYDC displayed excellent performance in the selective oxidation of C–H bonds of alkylbenzenes with high conversion (95.7%) and selectivity (96.6%). As an effective heterogeneous catalyst, FeW–PYDC demonstrates good reusability and structural stability.

多金属氧酸盐骨架作为多相催化剂选择性氧化烷基苯的 C-H 键

由于其热力学强度，开发用于高效和选择性氧化饱和 C-H 键的新催化剂具有重要意义。通过将 PW ₁₂ O ₄₀³^–、吡啶-2,5-二羧酸 (pydc) 和 Fe(III) 离子结合到一个骨架中，一种新的基于多金属氧酸盐的金属有机骨架，[HFe ₄ O ₂ (H ₂ O) ₄ (pydc) ₃ PW ₁₂ O ₄₀ ]·10.5H ₂ O ( FeW-PYDC )，通过水热法成功制备。有趣的是，FeW-PYDC具有三维多孔结构，其中 {Fe ₄O ₂ } 与 PW ₁₂ O ₄₀³^–单元互连。FeW-PYDC在选择性氧化烷基苯的 C-H 键方面表现出优异的性能，具有高转化率（95.7%）和选择性（96.6%）。作为一种有效的多相催化剂，FeW-PYDC表现出良好的可重复使用性和结构稳定性。
