An efficient synthesis of perfluoroalkenylated aryl compounds via Pincer-Pd catalyzed Heck couplings

Heck couplings of aryl halides with fluoroalkyl-substituted ethylenes catalyzed by Pincer Palladium complex were described. A variety of fluorous ponytail-substituted aromatics were obtained with moderate to excellent yields. Moreover, the catalyst can be easily separated from the reaction mixture by F-SPE technique and reused three times without significant loss of activity.
