Effective hydrolysis of epoxides and aziridines was conducted by heating them in water at 60 or 100 degrees C. Other types of nucleophile such as amines, sodium azide, and thiophenol could also efficiently open epoxides and aziridines in hot water. It was proposed that hot water acted as a modest acid catalyst, reactant, and solvent in the hydrolysis reactions.
