摘要： 以单氧给体乙酰碘苯[PhI(OAc)2]为氧源, 在无需轴向配体和有机溶剂的参与下, 离子型锰卟啉[MnⅢ(BF4)T(N-Me-4-Py)P][BF4]4和离子液体 [BMIM]BF4组成的多元离子液体体系, 在温和的反应条件下对苯乙烯的催化氧化表现出较高的活性(87%)和环氧苯乙烷选择性(90％), 并且有较好的底物普适性. 构筑的锰卟啉多元离子液体体系可以一定程度上抑制卟啉聚合和氧化降解等反应.

Abstract: Without the additional involvement of axial ligand and organic solvent, the ionic manganese porphyrin [MnⅢ(BF4)T(N-Me-4-Py)P][BF4]4(1d) immobilized in [BMIM]BF4 efficiently catalyzed the oxidation of styrene with a good activity(87% conv.) and epoxide selectivity(90%) under mild reaction conditions. The generality of 1d-[BMIM]BF4 system to the substrates of styrene derivatives with different electronical effects also lead to the pleasing results. The degradation of metalloporphyrin coming from the π-π stacking of porphyrin itself and the oxidation destruction was greatly suppressed in this built-up 1d-[BMIM]BF4 system.
