A new mixed-linker iron-based MOF VNU-20 [Fe₃(BTC)(NDC)₂·6.65H₂O] was solvothermally synthesized from 1,3,5-benzenetricarboxylic acid, 2,6-naphthalenedicarboxylic acid and FeCl₂. VNU-20 was utilized as a recyclable catalyst for the functionalization of coumarins with N,N-dimethylanilines via direct C–H bond activation. This Fe-MOF was found to be more active towards the coupling transformation than several conventional homogeneous and MOF-based heterogeneous catalysts. To the best of our knowledge, this is the first time that [Fe₃(CO₂)₇]_∞ SBUs are evaluated for their catalytic activity, and this transformation of coumarins is new.

通过铁-有机骨架作为可循环利用的催化剂，通过直接的C-H键活化来实现香豆素的新转变†

由1,3,5-苯三甲酸，2,6-萘二甲酸和FeCl ₂溶剂热合成新的基于混合链铁的MOF VNU-20 [Fe ₃（BTC）（NDC）₂ ·6.65H ₂ O] 。VNU-20可作为可循环利用的催化剂，通过直接的C–H键活化，将香豆素与N，N-二甲基苯胺官能化。发现该Fe-MOF比几种常规的均相和基于MOF的非均相催化剂对偶合转化更具活性。据我们所知，这是[Fe ₃（CO ₂）₇ ] _∞的第一次对SBU的催化活性进行了评估，香豆素的这种转化是新的。
