摘要: 合成了氯化-四(对-硝基)苯基卟啉锰[简称T(p-NO2)PPMn(Ⅲ)Cl],用光谱滴定法研究了中心原子与双原子分子及台N有机碱的轴向反应,计算了与有机碱反应的平衡常数及反应分子数,证明卟啉环上的吸电子取代基促进了Mn(Ⅲ)卟啉被还原,轴向配位还原能力顺序为T(p-NO2)TPPMn(Ⅲ)Cl>(β-NO2)PPMn(Ⅲ)Cl>photo-DMPrPorMn(Ⅲ)Cl>meso-MDBPTPPMn(Ⅲ)Cl>TPPMn(Ⅲ)Cl。

Abstract: A kind of porphyrinmaganese (Ⅲ) complex, meso-tetra (4-nitrophenyl) porphyrinman-ganese(Ⅲ) chloride was synthesized The adducts of this porphyrinmanganese (Ⅲ) complex with di atomic molecules such as CO, NOand some organic bases are studied by means of the spectroscopic method. The experimental results show that electron-attracting substituents such as nitro(NO2) on the porphyrin cycle can make the reduction process from Mn(Ⅲ) to Mn(Ⅱ) operate easily. In the presence of trace methanol, NO can reduce this porphyrinmnanganese(Ⅲ) complex.
