[TPPMn(Ⅲ)]2O在酸碱及氧化剂作用下的转化
Study on the Conversion of [TPPMn(Ⅲ)]2_O in the Existence of Acid-base or Oxidants
【摘要】 研究了μ-氧代双(四苯基卟吩合锰(Ⅲ))[TPPMn(Ⅲ)]2O在酸碱及氧化剂作用下的转化.[TPPMn(Ⅲ)]2O在固态或碱性介质中能稳定存在,在酸性或含水介质中转化为相应的单核锰卟啉TPPMn(Ⅲ)OH;在空气、H2O2或PhIO等氧化剂作用下,被氧化开环,紫外-可见光谱监测上述转化过程发现,对不同氧化剂,[TPPMn(Ⅱ)]2O转化的机理不同.
【Abstract】 The conversion of μ-oxo-bis [tetraphenylporphinatomanganese(Ⅲ)]2O is found to be stable in the solid state or in base medium, but be converted into corre sponding mononmagnanese(Ⅲ)porphyrin (TPPMn(Ⅲ)OH)in acid medium or water.[TPPMn(Ⅲ)]2O is oxided into the opening-ring compound by the oxidants such as oxygen in the air, H2O2 or PhIO .The different conversion mechanisms of [TPPMn (Ⅲ)]2O at different oxidants are found through monitoring the conversion processes with UV-Vis.
