分别研究了5-对[4-(间-吡啶氧基)丁氧基]苯基10,15,20-三苯基卟啉的Fe(Ⅱ).Fe(Ⅲ)和Co(Ⅱ)配合物的催化或载氧功能.以合成的金属卟啉、抗坏血酸和底物所组成的体系作为细胞色素P450单加氧酶的模拟体系,研究了在温和条件下对环已烷转变为环己酮、环己醇的催化作用,测定了这些体系的吸氧能力和羟化产物的产率.结果表明,尾式铁卟啉配合物Fe(Ⅲ)PyBPTPPCI 比其他简单相应铁卟啉配合物更为有效.用紫外可见光谱测定了尾式Co(Ⅱ)卟啉配合物的载氧能力,该模型化合物在室温苯溶液中呈现了可逆载氧能力,通过红外光谱进一步证明在氧合金属卟啉中的氧分子是以端基方式与中心金属Co 配位的.
The Fe (Ⅱ) complexes of 5-pairs of [4- (m -pyridyloxy) butoxy] phenyl 10,15,20-triphenylporphyrin were studied respectively. Catalyzed or oxygen-carrying function.According to the system of synthetic metalloporphyrin, ascorbic acid and substrate as the simulation system of cytochrome P450 monooxygenase, we studied the conversion of cyclohexane to cyclohexanone under mild conditions, Cyclohexanol.The results showed that Fe (Ⅲ) PyBPTPPCI was more effective than other simple iron porphyrin complexes The oxygen carrying capacity of the tail Co (Ⅱ) porphyrin complexes was determined by UV-visible spectroscopy. The model compounds exhibited reversible oxygen loading capacity in benzene solution at room temperature. The infrared spectra of the model compounds were further confirmed in the oxygenated metalloporphyrins Oxygen molecules are end-coordinated with the central metal Co.
