【摘要】 用分光光度法研究了一种新的尾式卟啉钴——间-[邻-(4-二乙胺基丁酰氨基)苯基]三苯基卟啉合钴(Ⅱ)[缩写为meso-MDBPTPP Co(Ⅱ)]与含N有机碱(咪唑,吡啶,脂肪胺等)的加合作用,测定了这些有机碱同卟啉钴的加合平衡常数。实验结果表明:原来是五配位的尾式钴卟啉与含N有机碱可一步形成1:1的加合物,从而生成六配位的配合物;同时发现伯胺类的平衡常数与BH~+的酸常数K_a之间的关系式为:lgK=3.82pK_a+9.58更多还原

【Abstract】 A new tailed porphyrin cobalt complex, meso-mono[o-(4-diethyl amino)butyramidophenyl]triphenyl porphyrin cobalt(Ⅱ), PCo(Ⅱ), is the fivecoordinate porphyrin cobalt(Ⅱ) complex. Its coordination properties with bases have been studied and axial coordinated constants for addition of these bases to PCo(Ⅱ) in benzene have been measured by spectral technique.更多还原
