A method has been developed for effecting rearrangements of allylacetoacetates to gamma,delta-unsaturated ketones (Carroll rearrangement) and allylaryl ethers to the corresponding allylphenols (Claisen rearrangement) under conditions of adsorption on aluminum oxide and silica gel. The method provides a sharp reduction of the temperature of these reactions and improvement of their efficiency.
