The reaction of 2-bromo-4-dibromomethylphenol with water in slightly aqueous (95%) 1,4-dioxane has been examined kinetically by using u.v. spectroscopy, which provides evidence for the transient formation of the quinone methide, 2-bromo-4-bromomethylenecyclohexa-2,5-dienone, during the hydrolysis. The final product is 3-bromo-4-hydroxybenzaldehyde. The rate of disappearance of starting material is
Enhancement of the conjugative electron-releasing power of the hydroxy-group shown by the kinetics of solvolysis of 2-bromo-4-dibromomethylphenol and of 2-bromo-4-dibromomethyl-anisole
