Addition of perfluorobutyl iodide to CC multiple bonds is efficiently achieved by sodiumdithioniteunder ultrasonic irradiation or phasetransferconditions. Perfluorobutyl substituted alkenes are obtained from the β-iodo-perfluoroalkanes resp.-alkenes by base-catalyzed elimination resp. reductive cleavage.
transformations can smoothly proceed via a radical process in the absence of an additional photocatalyst. The developed protocol employs alkenes and perfluoroalkyl iodides as readily available substrates and ethyl acetate as a green solvent, affording various perfluoroalkylated alkenes in satisfactory yields under mild conditions.
