【摘要】 本文用波谱及高压液相色谱（ＨＰＬＣ）方法研究了二氯代三－２－吡啶甲基胺的铁（Ⅲ）配合物（ＦｅＴＰＡＣｌ＿２ＣｌＯ＿４），三─６─甲基─２─吡啶甲基胺合铁（Ⅱ）与苯甲酸的配合物（Ｆｅ（Ⅱ）ＴＬＡＯＢｚＣｌＯ＿４）同单过氧化邻苯二甲酸六水合镁盐（ｍｏｎｏｐｅｒｏｘｙｐｈｔｈａｌｉｃａｃｉｄ，ｍａｇｎｅｓｉｕｍｓａｌｔｈｅｘａｈｙｄｒａｔｅ，即ＭＰＰＡ）的反应。提出了过氧键的两种断裂（即均裂和异裂）机理，分析了中心离子价态、配体结构等因素对反应机理的影响；并通过ＦｅＴＰＡＣｌ＿２ＣｌＯ＿４与间氯代过氧代苯甲酸（ｍｃＰＢＡ）的反应，研究了过氧酸结构对反应机理的影响。实验结果表明：就过氧酸中过氧键发生均裂的程度而言：三价铁配合物与过氧酸的反应＞二价铁配合物与过氧酸的反应；ＭＰＰＡ反应体系＞ＭＣＰＢＡ反应体系。更多还原

【Abstract】 The reactions of Fe￣（Ⅲ） TPACl₂ClO₄ and Fe￣（Ⅱ） TLAOB₂ClO₄ with MPPA were studied by the means of spectrometric method and HPLC. The two kinds of cleavage mechanism ofperoxyacids were proposed.The effect of variant valence of Iron complexes and the reactioncondition of the mechanism were studied;the effect of molecular structure of peroxyacids onthe cleavage of 0-0 bond was studied by the reaction of Fe TPACl₂ClO₄ with mCPBA. Theexperimental results indicated that homolysis of 0-0 bond of the reaction of Fe￣（Ⅲ） TPACl₂ClO₄with peroxyacid is much more pronounced than Fe￣（Ⅱ） TLAOB₂ClO₄ complexes;MPPA reactionsystem doos more than mCPBA reaction system.更多还原
