Manganese complexes of 5,15-diaryl-β-substituted-porphyrins were prepared and their behaviour as oxidation catalysts was studied. The role of the pyrrolic and meso-substituents on the activity and selectivity of these catalysts was studied to reveal new structure–activity relationships in these porphyrin-based epoxidation catalysts. The beneficial effect of the halogen atoms at the meso-phenyls is still observed with these catalysts but, for the first time, a strong dependence on the selectivity of the epoxide production was found to be dependent on the nature of the non-halogen substituents at the β-pyrrolic positions of the porphyrin.

5,15-二芳基-β-取代的卟啉锰 (III) 氯化物作为卟啉基环氧化催化剂中构效关系的探针

制备了5,15-二芳基-β-取代卟啉的锰配合物,并研究了它们作为氧化催化剂的行为。研究了吡咯和中间取代基对这些催化剂的活性和选择性的作用,以揭示这些基于卟啉的环氧化催化剂中的新结构-活性关系。使用这些催化剂仍然可以观察到中间苯基上卤素原子的有益作用,但首次发现对环氧化物生产选择性的强烈依赖取决于非卤素取代基的性质卟啉的β-吡咯位置。
