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．
The conversion of μ-oxobis (tetraphenylporphinato manganese (Ⅲ)) [TPPMn (Ⅲ)] 2O was studied under the influence of acid and alkali and oxidant. [TPPMn (Ⅲ)] 2O can be stably present in solid or alkaline media and converted into the corresponding mononuclear manganese porphyrin TPPMn (Ⅲ) OH in acidic or aqueous media. Under the action of oxidants such as air, H2O2 or PhIO, Oxidation ring-opening, UV-visible spectroscopy monitoring of the conversion process found that, for different oxidants, [TPPMn (Ⅱ)] 2O conversion mechanism is different.
