摘要

合成了一种新的具有氧化还原活性的钴（III）配合物，该配合物含有一个邻苯二酚双离子和两个4,4'-二甲氧基-2,2'-联吡啶配体。用核磁共振原位法研究了该配合物与抗坏血酸在惰性气氛中的还原反应。反应符合一级动力学，反应速率常数为1.1 × 10-3 s-1，并伴有作为模型药物的儿茶酚的释放。

Synthesis of a New Cobalt Complex with Catechol Dianion and Study of the Kinetics of Its Redox-Activated Dissociation

A new redox-active cobalt(III) complex with a catechol dianion and two 4,4'-dimethoxy-2,2'-bipyridine ligands was synthesized. The reduction of the complex with ascorbic acid in an inert atmosphere was studied by NMR spectroscopy in situ. The reaction followed the first-order kinetics with respect to the starting complex, had a rate constant of 1.1 × 10^–3 s^–1, and was accompanied by the release of catechol, which served as a model drug.
