Solvolysis of the tertiary alcohol, 5a, in 1,4-dioxane-water in the pr
esence of perchloric acid takes place mainly with water elimination. T
he ring opening and ring enlargement also occurred, but in a small pro
portion. In order to explain the observed behaviour, a reaction mechan
ism was proposed.
