摘　　要：A new fluorinated anionic surfactant Cl（CF2）6O（CF2）2SO3N（C2H5）4 was prepared and characterized. The application of the fluorosurfactant allowed the fluoroalkylation to occur in the water without adding organic solvent. The addition of perfluoroalkyl iodides 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.A new fluorinated anionic surfactant Cl（CF2）6O（CF2）2SO3N（C2H5）4 was prepared and characterized.
