H2O–1,4-dioxane and without an additional catalyst, the rearrangements of various types of cyclopropylcarbinols were attempted. It was found that the reactions generally gave homoallylic alcohols in good to very high chemical yields. Rearrangements of bicyclic or tricyclic cyclopropylcarbinols readily gave the desired ring-expanded cyclic homoallylic alcohols which are difficult to synthesize by other
