Studies on a New Tailed Porphyrinmanganese——The Reaction of a Tailed Porphyrinmanganese(Ⅲ)Complex wtth a Series of Organic Bases

采用光谱技术研究了一种新型尾式锰(Ⅲ)卟啉——氯化meso-—[邻-(4-二乙胺基丁酰胺基)苯基]三苯基卟啉合锰(Ⅲ)[筒作PMn(Ⅲ)C1]与有机碱的轴向反应,通过光谱滴定法测定了轴向反应在苯溶剂中的平衡常数.讨论了影响反应的因素.结果表明,这种尾式锰(Ⅲ)卟啉与脂肪胺的反应是氧化还原反应,与吡啶的反应是不完全的氧化还原反应,与咪唑的反应是轴向加合反应.

The reactions of a new tailed porphrinmangaanese complex, meso-mono-[o- (4-diethy-lamino)butyramidophenyl]triphenylporphyrin manganese ( Ⅲ ) chloride, PMn ( Ⅲ )Cl, with organic bases were studied and the equilibrium constants of the axial addition reactions for these bases to PMn( Ⅲ )C1 in benzene were measured by spectral technique. Experimental results demonstrated that the reaction of this PMn(Ⅲ )C1 with aliphatic amines is a redox reaction,with pyridine is an incomplete redox reaction, and with imidazole is an axial addition reaction , respectively. The factors affected these reactions were also studied.
