Benzeneselenenyl fluoride equivalent was generated in situ by the reaction of silver(I) fluoride with benzeneselenenyl bromide in dichloromethane under ultrasound irradiation. Treatment of internal alkynes with this reagent afforded 2-fluoro-1-alkenyl phenylselenides in moderate yields.

The oxidation of diphenyldiselenide with 4-iodotoluene difluoride (DFIT) in dichloromethane produces in situ an efficient phenylselenofluorinating agent of alkenes and internal alkynes.
