Ethylenediaminetetraacetato iron(III) [(EDTA)Fe(III)] has been shown to react with a series of four peroxycarboxylic acids and four alkyl hydroperoxides (YOOH; dry methanol solvent, 30 degrees C) by heterolytic O-O bond scission that accompanies the transfer of an oxygen atom to the iron(III) moiety [(EDTA)Fe(III) + YOOH----[(EDTA)(FeO)]+ + YOH]. A single linear free-energy relationship exists for both peroxycarboxylic acids and alkyl hydroperoxides when the logarithm of the second-order rate constant (kYOOH) for reaction of YOOH species with (EDTA)Fe(III) is plotted vs. the pKa of the YOH leaving group.
乙二胺四乙酸铁(III)[(EDTA)Fe(III)]已被证明可与一系列四种过氧羧酸和四种烷基氢过氧化物(YOOH;干燥甲醇溶剂,30℃)通过异裂O - O键断裂反应,该反应伴随着一个氧原子转移到铁(III)部分[(EDTA)Fe(III)+ YOOH→[(EDTA)(FeO)]⁺ + YOH]。当将YOOH物种与(EDTA)Fe(III)反应的二级速率常数(kYOOH)的对数与离去基团YOH的pKa作图时,过氧羧酸和烷基氢过氧化物都存在单一的线性自由能关系。
