The oxidation of diphenyldiselenide with ammonium peroxydisulphate is a very simple and efficient method to produce phenylselenium cations in the absence of nucleophilic counter ions. The reaction carried out in the presence of an olefin, in acetonitrile or propionitrile containing trifluoromethanesulphonic acid and water afforded the amidoselenenylation products in good yield.

The trans 1,2-phenylseleno acetate, acetamide, alcohol and nitrile of cyclohexane may be oxidized at selenium by halogens and the phenylseleno moiety displaced by halide to give high yields of 1,2 halide-containing products with cis geometry.

The low temperature oxidation of β-amido selenides with MCPBA affords the corresponding β-amido selenones. In situ treatment of the selenones with KOtBu gives N-acylaziridines in good to excellent yield.
