摘要: 对双吡唑烷B金属羰基配合物的电化学特性进行了系统研究.结果表明,吡唑环上的取代基极大的影响双吡唑烷B金属羰基配合物金属中心的峰电位E1/2.给电子取代基增强配体的配位能力且使金属中心的E1/2减小,而吸电子取代基减弱配体的配位能力使金属中心的E1/2增大.

关键词: 双吡唑烷, ⅥB金属羰基配合物, 循环伏安法

Abstract: The cyclic voltammetric behavior of ⅥBcarbonyl complexes containing bis(pyrazol-1-yl)alkanes has been investigated. It was found that the redox potentials(E1/2) of metal centers remarkably relate to the ability of electron donating of ligands. Metal centers with electron donating groups on the pyrazolyl rings are easier to be oxidized than those containing electron withdrawing groups.

Key words: Bis(pyrazol-1-yl)alkane, ⅥB metal carbonyl complexes, Cyclic voltammetry
