The acid-catalyzed hydrolysis of Me cyclohexanecarboxylate (in 1:1 and 1:3 dioxane-water), of all the dimethyl and Me H cyclohexanedicarboxylates (in 1:3 dioxane-water), and of Me cis-(I) and trans-4-tert-butylcyclohexanecarboxylate (II) (in 1:1 dioxane-water) has been studied and the Arrhenius activation energies and non-exponential factors have been determined The rate coefficients for the first stage of hydrolysis of the diesters were obtained by using the Wideqvist method (CA 50, 9113b). From the results for I and II an equatorial MeO2C is shown to react 4.8 times more rapidly than an axial MeO2C at 90°. On this basis the results for the other esters are discussed in relation to their possible conformations. The MeO2C group is more stable in the equatorial than in the axial conformation, but the results for acid-catalyzed hydrolysis of the trans 1,2-esters are best explained by assuming that the compound is diaxial. Polar effects in acid-catalyzed hydrolysis of the esters are small. Some of the results obtained by Cavell, et al. (CA 54, 18387e) for the alk. hydrolysis of the esters are discussed in the light of the results for the acid-catalyzed hydrolysis, and an attempt has been made to sep. polar effects from steric effects in alk. hydrolysis.
