aqueous dioxane the cyclopropylcarbinyl (1-X), endo-cyclobutyl (2-X) and homoallylic (3-X) derivatives (X = nucleofuge) react to give the same mixture of alcohols 1-OH and 3-OH by way of a common intermediate, the symmetrical homoallylic ion 22. This follows from a study of optically active reactants 1-X and 3-X and from the deuterium scrambling pattern in the products from deuteriated 1-X, endo-2-X
