用于合成烯丙基醇、烯丙基醚、乙酸酯和α，β-不饱和羰基化合物。

{ALF} For introduction of the phenylseleno group by Michael addition, phenylselenol can be generated in situ by borohydride cleavage: Synthesis, 664 (1980).

{ALF} For a comprehensive review of the preparation of ɑß-unsaturated carbonyl compounds and nitriles by selenoxide elimination, see: Org. React., 44, 1 (1993). Compare also Phenylselenenyl bromide, A11906 and Phenylselenenyl chloride, A12751.

{ALF} 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 ɑß-unsaturation into, e.g. ketones: J. Am. Chem. Soc., 97, 5434 (1975):

{ALF} 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):
