摘 要: | The axial coordinate water substitution reactions of alkylaquacobaloximes (alkyl=n-C3H7, n-C4H9, i-C4H9, n-C5H11, Br(CH2)3, PhCH2) by ammonia in aqueous solution were studied in the absence and presence of β-cyclodextrin (β-CD). The equilibrium constants were measured by UV-vis spectroscopy. It has been found that (i) comparing with that in the absence of β-CD, the equilibrium constant were influenced slightly in the presence of β-CD, (ii) with increasing electron-withdrawing ability of the alkyl groups, the equilibrium constants were increased.
