Abstract

A new redox-active cobalt(III) complex containing the 2-oxo-2Н-chromene-6,7-diolate dianion and 4,4'-dimethoxy-2,2'-bipyridine as ligands is synthesized. The reduction of the synthesized complex with ascorbic acid in an inert atmosphere is studied in situ by NMR spectroscopy. The reduction is shown to result in the release of 6,7-dihydrocycoumarin acting as a model drug. This process has the first order with respect to the initial complex.

二羟基香豆素的新钴配合物：合成及其氧化还原激活解离动力学

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 2-oxo-2Н-chromene-6,7-diolate 二离子和 4,4'-dimethoxy-2,2'-bipyridine 配体。在惰性气氛中，利用核磁共振光谱对合成复合物与抗坏血酸的还原过程进行了原位研究。研究表明，还原过程会导致作为模型药物的 6,7-二氢香豆素的释放。这一过程对于初始复合物而言是一阶的。
