Aqueous Fe~(IV)=O:Spectroscopic Identification and Oxo-Group Exchange

摘要

An aqua oxoiron(IV) species is believed to play important roles in environmental and catalytic chemistry,and has been proposed by some researchers as an alternative to HO~(centre dot) as the Fenton oxidant,that is,the intermediate produced in the reaction between Fe~(2+) and H_2O_2 in aqueous solution.The existence of a ferryl intermediate,most probably [(H_2O)_5Fe~(IV)=O]~(2+),has not been established independently in acidic and neutral solutions.
