Abstract

The reaction between H(2)O(2) and a pyridine-coordinated ferric porphyrin encapsulated by a cyclodextrin dimer yielded a hydroperoxoferric porphyrin intermediate, PFe(III)-OOH, which rapidly decomposed to oxoferryl porphyrin (PFe(IV)═O). Upon reaction with H(2)O(2), PFe(IV)═O reverted to PFe(III)-OOH, which was converted to carbon monoxide-coordinated ferrous porphyrin under a CO atmosphere. PFe(IV)═O in the presence of excess H(2)O(2) behaves as PFe(III)-OOH.

摘要

H(2)O(2)与吡啶配位的铁卟啉在环糊精二聚体的包裹下发生反应，生成过氧合铁卟啉中间体 PFe(III)-OOH，它迅速分解为氧代铁卟啉（PFe(IV)═O）。与 H(2)O(2)反应时，PFe(IV)═O 回复到 PFe(III)-OOH，在 CO 气氛下，它转化为一氧化碳配位的亚铁卟啉。在过量 H(2)O(2)存在下，PFe(IV)═O 的行为类似于 PFe(III)-OOH。
