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.

Fluoroalkylseleno groups are emerging groups that still suffer from a lack of efficient methods for introduction onto organic molecules. Herein, we describe an efficient method to perform reactions between in situ formed fluoroalkaneselenyl chlorides and organometallic reagents. With this strategy, various fluoroalkylselenolated molecules were easily obtained. Furthermore, the Hansch parameter of the

trifluoromethylation, the perfluoroalkyl anion reagents created by mixing C2F5I and n-C4F9I with tetrakis(dimethylamino)ethylene (TDAE) were effective in their nucleophilic reactions with aldehydes, ketones, imines, disulfides, and diselenides. Irradiation proved beneficial in the aldehyde and ketone reactions.

perfluoroalkyl selenoxides, selenones and selenoximines was possible through a selective oxidation of perfluoroalkyl selenoethers. Synthesis of perfluoroalkyl selenoxides was also described via a two-step one-pot reaction from selenocyanates. The perfluoroalkyl selenoximine family was synthesized. The Hansch-Leo parameters of the compounds were determined and some aryl perfluoroalkyl selenoxides were separated
