| 摘 要： | 通过在中性锰卟啉分子中引入季铵阳离子和PF6-阴离子,制备了离子型锰卟啉化合物MnTTMAPP]PF6]5,将其与bmim]BF4及bzmim]BF4混合构成锰卟啉功能化的多元离子液体复合体系(MnPy-MIL).实验发现,该体系可以高活性高选择性地催化苯乙烯及其衍生物的环氧化反应.与传统中性锰卟啉催化体系相比,离子型锰卟啉的抗氧化降解能力提高,卟啉自身聚合受到抑制,催化反应无需有机溶剂和轴向配体的参与,同时催化剂可以循环使用.少量水的存在可以提高MnPy-MIL体系的催化性能.

| Abstract: | The ionic manganese porphyrin bearing trimethylbenzylammonium cation and PF-6 anion (MnTTMAPP PF6 5) was mixed with the ionic liquids of bzmim BF4 and bmim BF4 to build up a manganese porphyrin-functionalized multi-component ionic liquid (MnPy-MIL),which was used as a catalytic system for expoxidation of styrene and its derivatives with oxidant PhIO. Compared with the traditional neutral manganese porphyrin,the MnPy-MIL system has advantages of suppression of oxidation degradation and self-aggregation,recyclability,and no requirements of additional axial ligands and organic solvents. The presence of a small amount of water could improve the catalytic performance of MnPy-MIL. |
