The ultrasonic irradiation of water was effected with 280-, 610-, and 800-kHz transducers at several intensities. Conditions were varied by utilization of different initial pH, temperatures, and gaseous atmospheres in the sealed irradiation vessels. The rate of hydrogen peroxide formation was followed by titrimetric and spectrophotometric analyses. The nature of the gas and the sound intensity were established as the controlling rate factors. Irradiations of carbon tetrachloride in saturated aqueous solutions were accomplished under conditions identical with those applied to pure water. Products included carbon monoxide, carbon dioxide, hypochlorous acid, hydrochloric acid, and hexachloroethane. Product ratios were to some extent intensity dependent. Rates were likewise dependent on intensity but were unaffected by the gaseous atmospheres employed. Di-/z-butyl sulfide (1) was subjected to the standard irradiative conditions while suspended in pure water and in saturated aqueous solutions of carbon tetrachloride. Little rate or product difference was discernible from the two media, or from the change from oxygen to argon atmosphere. The principal product under all conditions was di-n-butyl sulfoxide (2) . Minor products included n-butylsulfonic acid (5), butyric acid, carbon monoxide, ethylene, acetylene, and methane. The sources of these materials were explored and a mechanistic pathway is presented which accommodates the consolidated information gathered from the irradiations of water and aqueous solutions of carbon tetra-

An epoxide ring opening by an intramolecular nucleophilic attack of an amide group was utilized to synthesize 2-azanorbornan-6-ols and 2-azaadamantan-4-ols. The spectral identification of these compounds is described.
