Abstract: Perfluoroalkylzinc iodides or bromides which 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 ...
