铁卟啉化合物的合成及其催化环己烷羟基化反应的研究

Studied on Synthesis of Ironporphyrins and Cyclohexane Hydroxylation Catalyzed by Ironporphyrins

合成了１５种卟啉环上具有不同取代基和纵轴上具有不同配位基的ＴＲＰＰＦｅ＾ⅢＣｌ和ＴＰＰＦｅ＾ⅢＸ，从反应速率，反应产率和产物选择性等方面考察了卟啉环上取代基Ｒ和纵轴配位基Ｘ对这些铁卟啉在温和条件下催环已烷羟基化反应催化性能的影响，还研究了反应溶剂、反应温度以及有机碱等环境因素对铁卟啉催化遥影响，获得了一些新的结果和规律。

15 iron (Ⅲ) porphyrin compounds, TRPPFeⅢ Cl with different substituent R on porphyrin ring and TPPFeⅢ X with different axial ligand X, are synthesized. The cyclohexane hydroxylations under room temperature and atomsphere pressure catalyzed by these porphyrins are studied. The substituent R on porphyrin ring and axial ligand X are found to affect the yields, rates and selectivities of the hydroxylations. The effect of some reaction conditions such as solvent, temperature as well as addition of organic bases on the catalytic properties of iron(Ⅲ) -porphyrins is also discussed.
