摘　　要：利用一种已知的八乙基卟啉西佛碱配体Ｃ４３Ｈ５１Ｎ５合成了相应的钴（Ⅱ）配合物，其化学结构用谱学方法表征，研究了配位反应动力学，在６５～８０℃下，反应对卟啉西佛碱配体为一级，对钴盐为１／２级．测得了配位反应动力学方程和表观活化能，对反应机理进行了讨论．A cobalt (Ⅱ) complex was synthesized using the known ligand of mesooctaethylporphyrin Shiff-base, C43H51N5 (abbreviated to H2OEPSB). The complex was confirmed by spectra methods. The dynamics of complexation reaction was studied. The reaction rate law was determined to be first-order with respect to H2OEPSB and half-order forcobalt (Ⅱ) salt at 65～80℃ and the apparent activation energy was found to be 88.16 kJ.mol-1. The possible complexation reaction mechanism was proposed.
