  • Reagent for ɑ-phenylselenation of enolates. The products are readily oxidized to the selenoxides which undergo ambient temperature Cope-type elimination, providing a mild method for the introduction of ɑ?-unsaturation into, e.g. ketones: J. Am. Chem. Soc., 97, 5434 (1975):
  • For a comprehensive review of the preparation of ɑ?-unsaturated carbonyl compounds and nitriles by selenoxide elimination, see: Org. React., 44, 1 (1993). Compare also Phenylselenenyl bromide, A11906 and Phenylselenenyl chloride, A12751.
  • Oxidation of diphenyl diselenide by persulfate in the absence of a nucleophilic counter-ion generates the phenylselenium cation, which adds to alkenes. Molecules with a suitably placed nucleophilic site (alkene, hydroxyl, carbonyl, carboxyl, etc.) can then undergo intramolecular cyclization: J. Org. Chem., 55, 429 (1990); J. Chem. Soc. Perkin 1, 1989 (1993); Synlett, 373 (1994):
