## Abstract __Se__βPhenyl selenocarboxylates have been conveniently prepared from (phenylseleno)acetylenes by treatment with __p__βtoluenesulfonic acid monohydrate in dichloromethane. This easy conversion is compatible with a broad range of oxygenβ and nitrogenβcontaining functional groups. The __S
In a recent communication, Hartzell and Paige (1) reported that the sodium metaperiodate oxidation of ethylene episulfide in aqueous methanol g8ve the oorrezponding episulfoxide. This method, however, afforded impure materials in low yields when appl%ed to the syntheses of substituted ones and the i
