摘要：

Rates of acid-catalyzed hydrolysis of 5- to 8-membered ring benzophenone acetals (1-4) in 80% dioxane-water(v/v) were dependent upon the ring size and the ring-substituted methyl group as well as the condensed-rings. These kinetic results are interpreted in terms of the ring strain, the stereoelectronic effects, and the hydrophobicity.
