Trifluoromethylselenolation and Fluoroalkylselenolation of Alkenes by Electrophilic Addition

Fluoroalkylselenylated compounds are still underused due to a lack of efficient synthetic methods. Herein, we describe an efficient synthesis of α-chloro-β-fluoroalkylselenolated molecules through electrophilic addition of in situ preformed fluoroalkylselenyl chlorides onto alkenes. The obtained compounds constitute valuable building blocks for further applications.
