Salomaa, Pentti published the artcileHydrolysis of 1,3-dioxolane and its alkyl-substituted derivatives. I. Structural factors influencing the rates of hydrolysis of a series of methyl-substituted dioxolanes, Safety of 2,2,4-Trimethyl-1,3-dioxolane, the publication is Acta Chemica Scandinavica (1961), 871-8, database is CAplus.

The exptl. techniques for the rate studies were dilatometric, for dioxolane derivatives which carried one or two Me groups at the 2-position, and titrimetric, for those derivatives that did not carry substituents at the 2-position. Based on the magnitude of the activation entropies, it was probable that the dioxolanes hydrolyzed by essentially the same mechanism as acyclic acetals. The introduction of a methyl group at the 2-position increased the rate of hydrolysis of dioxolanes by a factor of 103-104, primarily due to low activation energies. A second Me group at the 2-position increased the rate by another power of 10. The addition of one or more Me groups as substituents at the 4- and 5-position had a more complex influence on the rate of hydrolysis, most likely because of interaction of steric strain and polar effects. The polar factors involved were similar to those observed in acyclic acetals. The steric strain considerations which involved the partial 2,3-double bond after proton uptake at the 1-position also permitted distinguishing between cis- and trans-2,4-dimethyl-1,3-dioxolane, the cis form hydrolyzing about 4 times faster than the trans form.
