A new synthesis of perfluoroalkylmethyloxiranes and perfluoroalkylmethylaziridines is accomplished by addition of allylalcohol or allylamine to iodoperfluoroalkanes in the presence of potassium or sodium hydroxide.

Ultrasound-Promoted Selective Perfluoroalkylation on the Desired Position of Organic Molecules
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
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.
