- 中文摘要: Solubilities are reported for three Co(III) complexes of 2-aminophenol, 2-amino-4-nitrophenol and 6-amino-2,4- dimethylphenol. Transfer chemical potentials have been derived from appropriate solubility measurements in aqueous methanol. The trends in transfer chemical potentials are discussed in terms of the nature of the coordinated ligands and are compared with those for selected of other inorganic Co(III) complex ions. The kinetics of base hydrolysis of Co(III) complexes in aqueous methanol solutions are described and the change in the activation barrier.delta./sub m/△G/sup #/ is determined. Solvent effects on reactivity trends are analyzed into initial state and transition state components. The small decrease in the rate constant, with increasing proportion of methanol, is ascribed to a greater effect of solvent on the initial state.
