heterogeneous photocatalytic system for the switchable divergent perfluoroalkylation of terminalalkynes has been developed by employing mesoporous graphitic carbon nitride (mpg-CN) as a recyclable, nontoxic, and heavy-metal-free photocatalyst. Regulating the reaction solvents allowed libraries of perfluoroalkylated alkynes, alkenes, and alkenyl iodides to be synthesized in good-to-high yields. Furthermore

terminal alkynes driven by the noncovalent interaction between a thymol anion and fluoroalkyl iodides. By precisely tuning the reaction solvent, a wide range of 37 structurally diverse perfluoroalkylated alkynes and alkenes, including ibuprofen, empagliflozin, galactose, isoxepac and indomethacin, were obtained in up to 92% yields. Mechanistic studies reveal the formation of EDA complexes between the

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.
