制备并表征了一种新型的氟化阴离子表面活性剂Cl(CF 2)6 O(CF 2)2 SO 3 N(C 2 H 5)4。含氟表面活性剂的应用使氟烷基化在水中发生而无需添加有机溶剂。在含氟表面活性剂的存在下,在水中在Na 2 S 2 O 4的引发下,将全氟烷基碘化物与烯烃和炔烃加成,得到相应的加合物,收率良好或优异。含氟表面活性剂适用于自由基加成过程。
Radical Addition of Perfluoroalkyl Iodides to Alkenes and Alkynes Initiated by Sodium Dithionite in an Aqueous Solution in the Presence of a Novel Fluorosurfactant
fluoroalkylation to occur in the water without adding organic solvent. The addition of perfluoroalkyliodides with olefins and alkynes under the initiation of Na2S2O4 in water in the presence of the fluorosurfactant gave the corresponding adducts in good to excellent yields. The fluorosurfactant was suitable for a radical addition process.
