Abstract

Electron spectroscopy shows that the protonation of ferrocenylcrboxylic and ferrocenylacetic acids is accompanied by the redox isomery of generated ferrocenecarbenium ions. The effect the nature of the metal complexes, Brønsted acids, and solvents has on the rate of redox isomery is determined. It is shown kinetically that the stabilization of the acylium ion FcC⁺O (where Fc is ferrocenyl) due to coordination with FcCOOH is a result of the extreme dependence of the rate of redox isomery on the concentration of FcCOOH.

布朗斯台德酸二茂铁羧酸质子化的特征

摘要

电子光谱表明，二茂铁基苯甲酸和二茂铁基乙酸的质子化伴随着生成的二茂铁碳鎓离子的氧化还原异构体。确定了金属络合物，布朗斯台德酸和溶剂的性质对氧化还原异构体速率的影响。动力学上显示，由于与FcCOOH的配位而导致的lium离子FcC ⁺ O（其中Fc为二茂铁基）的稳定化是氧化还原异构体速率对FcCOOH浓度的极端依赖性的结果。
