  reaction of 1 with the hydroperoxides (t)BuOOH and KHSO(5), the common mechanism is one of heterolytic scission of the O-O bond. The water soluble and easy to oxidize substrate 2,2'-azobis(3-ethylbenzithiazoline-6-sulfonate (ABTS), was employed to substantiate the mechanistic proposal. Reactions were carried out under pseudo-first order conditions for [ABTS] >> [hydroperoxide] >> [1], and were monitored

  [Ru（III）（edta）（H（2）O）]（-）（1）（edta =乙二胺四乙酸盐）与叔丁基氢过氧化物（（t）BuOOH）和过硫酸氢钾（KHSO（5））的反应为研究人员使用停止流技术在固定pH值为6.1的条件下动力学研究了氧化剂浓度和温度（10-30摄氏度）的函数。通过使用整体动力学分析技术来分析动力学结果。发现该反应由两个步骤组成，涉及快速形成[Ru（III）（edta）（OOR）]（2-）中间体，该中间体随后进行溶解裂解形成[（edta）Ru（V）= O ]（-）。由于[EDRu（V）= O]（-）在1与氢过氧化物（t）BuOOH和KHSO（5）的反应中几乎是定量生成的，因此常见的机理是OO键的杂合断裂。水溶性且易氧化的底物2,2'

• Mechanisms of Iron Porphyrin Reactions with Peroxynitrite
  作者：Jinbo Lee、Julianne A. Hunt、John T. Groves

  Peroxynitrite (ONOO-)is a major cytotoxic agent that has been implicated in a host of pathophysiological conditions; it is therefore important to develop therapeutic agents to detoxify this potent biological oxidant, and to understand the modes of action of these agents. Water-soluble iron porphyrins, such as 5,10,15,20-tetrakis(N-methyl-4'-pyridyl)porphinatoiron(III) [Fe(III)TMPyP] and 5,10,15,20-tetrakis-(2,4,6-trimethyl-3,5-sulfonatophenyl)porphinatoiron(III) [Fe(III)TMPS], have been shown to catalyze the efficient decomposition of ONOO- to NO3- and NO2- under physiological conditions. However, the mechanisms of ONOO- decomposition catalyzed by these water-soluble iron porphyrins have not yet been elucidated. We have shown that there are two different pathways operating in the catalytic decomposition of ONOO- by FeTMPyP. Fe(III)TMPyP reacts rapidly with ONOO- to produce oxoFe(IV)TMPyP and NO2 (k approximate to 5 x 10(7) M-1 s(-1)). The oxoFe(IV) porphyrin, which persisted throughout the catalytic decomposition of ONOO-, was shown to be relatively unreactive toward NO2- and NO2-. This oxoFe(IV) porphyrin was also shown to react with ONOO- (k = 1.8 x 10(6) M-1 s(-1)), and it was this oxoFe(TV)-ONOO- reaction pathway that predominated under conditions of excess ONOO- with respect to Fe(III)TMPyP. The competition between the two pathways explains the highly nonlinear relationship observed for k(cat) with respect to ONOO- concentration. Fe(III)-TMPyP is also known to catalyze the dismutation of the ONOO- precursor superoxide (O2(-.)), and using stopped-flow spectrophotometry, the rate of Fe(III)TMPyP-catalyzed O-2(-.) dismutation has been determined to be 1.9 x 10(7) M-1 s(-1) by direct measurement. A detailed mechanistic understanding of how iron porphyrins function in the catalytic decomposition of both ONOO- and O-2(-.) may prove essential in the exploration of the chemistry and biology of these reactive oxygen species, and in understanding the biological activity of these metalloporphyrins.
