| 摘 要： | 文章合成了两个新的手性卟啉配合物-尾式L（D）-苯丙氨酸铁Hh啉，并通过紫外光谱和质谱对其结构进行了表征。利用这两个化合物进行了苯乙烯的催化环氧化研究，分别考察了不同溶剂和不同轴向配体的影响。实验结果显示尾式L（D）-苯丙氨酸铁卟啉催化苯乙烯氧化的产物不具有对映体选择性。在不同溶剂中的环氧化物产率：乙腈〉二氯甲烷〉甲醇。在不同轴向配体作用下的产率为：吡啶〉4．硝基咪唑〉咪唑。

| Abstract: | Two new chiral porphyrin complexes named tail L(D)-phenylalanine iron(Ⅲ) porphyrin were synthesized and characterized by mass spectrometry and ultraviolet-visible spectroscopy.Catalytic epoxidation of styrene with these iron porphyrins were investigated in different solvents and different axial ligands conditions.Experimental results showed tail L(D)-phenylalanine iron(Ⅲ) porphyrin exhibited no enantioselectivity in the catalytic epoxidation of styrene.The epoxidation yield in different solvents flows an order of acetonitrile> dichloromethane > methanol;while the yield order in the presence of different axial ligands is pyridine> 4-nitro-imidazole> imidazole. |
