A detailed study of the ionization equilibrium between ferrocenyl alcohols and α-ferrocenyl carbocations in aqueous sulfuric acid has been performed by spectral methods. The spectral characterization of the carbocations, the extent of their formation as a function of the proton-donor ability of the solvent, and the determination of the equilibrium constants are reported. The behavior of ferrocenyl alcohols as indicators compared to that of triarylmethanols is discussed. The transmission of the polar effects of the heteroannular substituents, the heteroannular bridging of an α-hydroxytrimethylene chain, and the high charge delocalization power of the carbocation are also examined.

Abstract

A detailed study of the ionization equilibrium between ferrocenyl alcohols and α-ferrocenyl carbocations in aqueous sulfuric acid has been performed by spectral methods. The spectral characterization of the carbocations, the extent of their formation as a function of the proton-donor ability of the solvent, and the determination of the equilibrium constants are reported. The behavior of ferrocenyl alcohols as indicators compared to that of triarylmethanols is discussed. The transmission of the polar effects of the heteroannular substituents, the heteroannular bridging of an α-hydroxytrimethylene chain, and the high charge delocalization power of the carbocation are also examined.
