Abstract An amine-functionalized metal organic framework (MOF) was used as highly efficient and recyclable heterogeneous catalyst for Knoevenagel condensation of various aromatic aldehydes and ketones in ethanol. The catalytic efficiency was demonstrated by the high conversion of the reactants with 100 % selectivity under microwave (µW) irradiation, while dramatically reduced the reaction time as compared to the conventional heating method. Importantly, the MOF maintained its structural integrity after catalytic reactions and it could be reused several times without remarkable loss of activity.

使用胺官能化金属有机骨架的各种醛和酮的简便微波辅助 Knoevenagel 缩合

摘要 采用胺官能化金属有机骨架（MOF）作为高效、可回收的多相催化剂，用于各种芳香醛和酮在乙醇中的Knoevenagel缩合反应。反应物在微波 (µW) 照射下具有 100% 选择性的高转化率证明了催化效率，同时与传统加热方法相比，反应时间显着减少。重要的是，MOF 在催化反应后保持其结构完整性，并且可以多次重复使用而不会显着降低活性。
