摘要
本文用电化学及光谱电化学方法研究了钴卟啉与苄基氯的相互作用,表明形成有σ钴—碳键的辅酶B_(12)模型化合物的前提条件是钴卟啉的中心钴氧化态必须降低到I价.讨论了σ钴—碳键的形成和解离与电位的关系,现场检测到辅酶B_(12)模型化合物的形成和解离的紫外可见光谱,提出了钴卟啉与苄基氯的ECE作用机理.
The reaction of CoTPP with Ph0H_2Cl is studied by electrochemistry and spectroelectrochemistry. The results show that the essential condition for forming the σ cobalt-carbon bond-containing models is the central cobalt in cobalt-porphyrin reduced to lower valence (such as+1). The relation between the formation and dissociation of cobalt-carbon bond and electric potential is discussed in detail and the mechanism of reaction of CoTPP with PhCH_2Cl is also descried.
