关于以金属卟啉为催化剂的烷烃的模拟生物氧化研究,虽有零星报道,但还缺少系统的研究.我们根据生物氧化的一般原理,研究了金属卟啉对环己烷定向氧化的催化作用.我们利用分子氧-抗坏血酸-金属卟啉-环己烷模拟生物氧化体系,于常温常压下实现了环己烷被氧化成环己醇和环己酮的反应,反应中无其他氧化产物生成.血晶(氯化高铁血红素)和合成的四苯基卟啉的Fe,Co,Mn络合物有催化活性,其中以血晶最好. 血晶按文献[4]提取.中位四苯基卟啉(TPP)按Adler法合成.TPP的Fe,Co,Mn及Cu络合物用Rothemund法制备.这些化合物及其纯度分别用紫外光谱、红外光谱和
However, there is no systematic research on the simulated biooxidation of alkanes catalyzed by metalloporphyrin.We have studied the catalytic effect of metalloporphyrins on the directional oxidation of cyclohexane according to the general principle of biological oxidation. We use the molecular oxygen - ascorbic acid - metalloporphyrin - cyclohexane simulated biological oxidation system, at room temperature and pressure to achieve the oxidation of cyclohexane to cyclohexanol and cyclohexanone reaction, the reaction was no other oxidation products. Crystalline (hemin) and synthetic tetraphenylporphyrin Fe, Co, Mn complex catalytic activity, of which the best blood crystal blood crystal [4] extracted by the tetraphenyl The porphyrin (TPP) was synthesized by Adler method and the Fe, Co, Mn and Cu complexes of TPP were prepared by the Rothemund method.The purity of these compounds and their complexes were determined by UV, IR and
