Copper-catalyzed decarboxylative difluoroalkylation and perfluoroalkylation of α,β-unsaturatedcarboxylicacids is described. Promoted by dialkyl phosphite, this novel reaction affords fluoroalkylated motifs with excellent stereoselectivity and broad substrate scope under mild reaction conditions from readily available fluoroalkyl iodides and bromides. Preliminary mechanism study suggests that radical

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.
