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。
In this paper, the iron (Ⅲ) complexes of dichloro-3-picolylamine (FeTPACl_2ClO_4), 3-6-methyl-2-picolylamine were studied by HPLC and high performance liquid chromatography Reaction of Iron (Ⅱ) Complex with Benzoic Acid (Fe (Ⅱ) TLAOBzClO_4) with Monoperoxyphthalic Acid, Magnesium Salicylate (MPPA). The mechanism of two kinds of cleavage (ie, homogeneous cleavage and cleavage) of peroxy bond was put forward. The influence of valence of central ion, ligand structure and other factors on the reaction mechanism was analyzed. The effects of FeTPACl_2ClO_4 and m-chloroperoxybenzoic acid mcPBA) reaction, the peroxy acid structure of the reaction mechanism. The experimental results show that the reaction of trivalent iron complex with peroxyacid> the reaction of divalent iron complex with peroxyacid; MPPA reaction system> MCPBA reaction system.
