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.
