EFFECT OF A FERROCENYL SUBSTITUTE ON THE FUNCTIONAL GROUPS IN THE BENZENE RING,
Abstract:
The dissociation constants K-a and K-b were obtained for several ferrocenyl substituted benzoids and were compared with these constants for amino and hydroxy substituted benzoids. The K-b of p-Ferrocenylaniline is 3 times greater than that of aniline, and 17 times greater than that of p-aminodiphenyl xenylamine the K-b of m-ferrocenylanaline is 23 as great as the p- isomer. Similar results were obtained by the comparison of ferrocenylamine and ferrocenylphenol with phenol and p-hydroxydiphenyl p-phenylphenol, indicating that the ferrocenyl group introduced into the benzene ring behaves as a distinctly expressed substitute of the first order.
