摘要
本文报道了以CH_2Cl_2为溶剂,μ-氧-双四苯基卟吩合铁(Ⅲ)[(TPPFe)_2O]分别在亚碘酰苯(PhIO),H_2O_2和空气氧存在下转化为氯合、四苯基卟吩合铁(Ⅲ)(TPPFeCl)的反应.动力学初步研究表明在H_2O_2或PhIO存在下对(TPPFe)_2O为一级反应,而在空气氧中则为零级反应.反应速率常数与反应温度的关系符合Arrhenius方程式.根据动力学数据提出了该反应的可能机理.
The kinetic study on the conversion of (TPPFe)2O to TPPFeCl is reported in this paper. In the presence of oxidant PhIO or H2O2 this conversion is first order for (TPPFe)2O, but in the presence of air this conversion is zero order for (TPPFe)2O. The temperature dependence of the rate constant is consistant with Arrhenius equation. Based on these results the probable mechanisms for this conversionare suggested.
