The treatment of diselenides with different perfluoroalkyl iodides in the presence of sodium hydroxymethanesulfinate led to perfluoroalkyl selenides in fair to good yields. The reaction between benzyl perfluorooctyl selenide and chlorine, or sulfuryl chloride, gave rise to the corresponding selenyl chloride and represents an easy route to perfluoroalkylselenyl chlorides.

organoheteroatom stannanes containing elements of the groups 15 (P, As) and 16 (Se) with perfluoroalkyl iodides (RfI) was studied. Herein, a one-pot two-step reaction to form P–Rf, As–Rf and Se–Rf bonds is reported. The stannanes n-Bu3SnZPhn (Z = P, As, Se; n = 1–2) were generated in situ by the reaction of the PhnZ− anion with n-Bu3SnCl. The cross-coupling reactions of these stannanes with RfI afforded
Perfluoroalkyl-selenation of olefins has been performed by the reaction of diphenyl diselenide with sodium borohydride followed with perfluoroalkyl halides (RfX) and olefins where one electron transfer from phenylseleno anion to RfX occurs, generating perfluoroalkyl and phenylseleno radicals.
