Perfluoroalkylzinc iodides or bromides wich were prepared from perfluoroalkyl iodides or bromides and zinc powder in N,N-dimethylformamide or tetrahydrofuran with ultrasonic irradiation were found to behave as potential perfluoroalkylating reagents for the preparation of a wide variety of perfluoroalkylated compounds.Especially, the ultrasound-promoted asymmetric induction with perfluoroalkyl group on the asymmetrical carbon was achieved by the reaction of perfluoroalkyl halides with optically active enamines in the presence of zinc powder and a catalytic amount of dichlorobis(?-cyclopentadienyl)titanium.
ULTRASOUND-PROMOTED HYDRPERFLUOROALKYLATION OF ALKYNES WITH PERFLUOROALKYLZINC IODIDE AND COPPER(I) IODIDE

, p. 1453 - 1454 (2007/10/02)
The reaction of perfluoroalkyl iodides with terminal alkynes and ultrasonically dispersed zinc in the presence of copper(I) iodide proceeded smoothly to give the corresponding vinyl perfluoroalkylides in good yields.
PALLADIUM-CATALYZED CROSS-COUPLING REACTIONS BETWEEN ALLYL, VINYL OR ARYL HALIDE AND PERFLUOROALKYL IODIDE WITH ZINC AND ULTRASONIC IRRADIATION
Kitazume, Tomoya,Ishikawa, Nobuo
, p. 137 - 140 (2007/10/02)
The reactions of perfluoroalkyl iodides with allyl, vinyl or aryl halides with ultrasonically dispersed zinc in the presence of palladium catalyst proceeded smoothly to give the corresponding allyl, vinyl or aryl perfluoroalkylides in a good yield.
