Ferroceneboronic acid has been characterized by its UV and NMR spectrum and its dissociation constant in water/ethanol solvents has been determined. The kinetics of protodeboronation have been studied in the same solvents containing moderate concentrations of sulfuric acid; the H0 acidity function has been evaluated throughout the range of the reaction media used. The log of the rate of reaction of ferroceneboronic acid depends linearly with unit slope on H0. The solvent hydrogen isotope effect, the temperature dependence and the nature of acid catalysis have also been investigated. The reaction probably proceeds by an A-SE2-type mechanism.

Abstract
Ferroceneboronic acid has been characterized by its UV and NMR spectrum and its dissociation constant in water/ethanol solvents has been determined. The kinetics of protodeboronation have been studied in the same solvents containing moderate concentrations of sulfuric acid; the H0 acidity function has been evaluated throughout the range of the reaction media used. The log of the rate of reaction of ferroceneboronic acid depends linearly with unit slope on H0. The solvent hydrogen isotope effect, the temperature dependence and the nature of acid catalysis have also been investigated. The reaction probably proceeds by an A-SE2-type mechanism.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
