摘要：

The kinetics of the isomerization of cis-[Co(en)2(OAc)2]ClO4, were studied as a function of added sodium acetate in acetic acid in the range 68.8-84.5° by observing the absorbance decrease at 20.00 kK. It was found that sodium acetate retarded the rate of isomerization and the first-order rate constant appeared to have an acetate dependence of the form [formula omitted] where Ki, is the ionization constant for sodium acetate in acetic acid. The decreased rate is attributed to formation of an acetate ion pair that is less reactive than the perchlorate ion pair initially present. It is proposed that the isomerization within the ion pairs involves a solvent-assisted dissociation. © 1969, American Chemical Society. All rights reserved.
