Cycloaddition-rearrangement reactions of methyl cyclohexenyl ethers with p-bromobenzenesulfonyl azide in neat homogeneous admixture are substanially accelerated by low-wattage ultrasound. Using ultrasound approximately the same yields of rearranged products are obtained in less time at lower temperature than observed at ambient sonic frequencies and elevated temperature. A previously unreported product structural type has also been found.
