Alkenyl, allyl, and alkynylstannanes react with perfluoroalkyliodides in the presence of a catalytic amount of Pd(PPh3)4 to give alkenes and alkynes bearing perfluoroalkyl group.

smoothly with enolate anions of active methylene compounds such as 2-methyl-1,3-cyclopentanedione, ethyl 2-methylacetoacetate, and ethyl2-oxocyclopentanecarboxylate in a polar solvent to afford O- and C-perfluoroalkylation products in moderate yields, ratios O-/C-Rf products depending on the reaction temperature. Anions of diethyl 2-methylmalonate and 2-nitropropane afforded C-Rf-compounds only.
