| 中文摘要: |
| 单加氧酶细胞色素P-450在生物体中温和条件下活化分子氧,选择性地催化氧化碳氢化合物,其活性中间体可能是氧络铁原卟啉Ix的配合物。锰卟啉配合物也在温和条件下活化分子氧,选择性地催化氧化碳氢化合物,其活性中间体也可能是氧络锰卟啉配合物,是细胞色素P-450的很好的模型体系。目前人们已用一系列的氧化剂,诸如氧化碘苯(PhIO)、NaOCl、KHSO_5、RCOOOH、HCIO_4和HIO_4将三价的锰卟啉氧化为氧络锰卟啉。本实验 |
| 英文摘要: |
| Oxo-manganese-porphyrin is prepared by the reaction of (p- Cl) TPPMnCl, which has been prepared before in our laboratory, with aqueous solution of 5% NaCIO in dichloromethane, in which (t-Bu)4NCl acts as the phase-transfer reagent. The compound, (p-Cl)TPPMn(O)Cl, is characterized by ESR spectrum and UV- Visible spectrum. The reactivity of the oxo- manganese- porphyrin with different kinds of olefines are studied. The results show that for the olefines studied, the bigger the space-barrier of an olefine, the slower the velocity of the reaction of (p-Cl)TPPMnCl(O)Cl with the olefine, that is V(acrylic acid) >V(maleic anhydride) >V(cyclohexene)>V(maleic acid)>V (norborene-2,3-dicarboxylic anhydride). |
