The present invention is directed to a process for the reaction of a perfluoroalkyl iodide of the formula CF3(CF2)h-I, wherein h is an integer from 4 to 18, with a compound having a terminal olefinic group. The reaction is conducted in an aqueous medium containing a water-soluble solvent and in the presence of dithionite ion at a temperature of from 0 to 40°C and at a pH greater than 7Ø The perfluoroalkyl iodide is used in a process for the preparation of a perfluoroalkyl-allyloxy and perfluoroalkyl-iodopropyloxy-substituted polyaminoacid.
La présente invention porte sur un procédé de réaction d'un iodure de perfluoroalkyle de la formule CF3(CF2)h-I, dans laquelle h est un entier relatif de 4 à 18, avec un composé ayant un groupe oléfinique terminal. La réaction est effectuée dans un milieu aqueux contenant un solvant hydrosoluble et en présence d'un ion de dithionite à une température de 0 à 40.degrés.C et à un pH supérieur à 7Ø L'iodure de perfluoroalkyle est utilisé dans un procédé de préparation d'un polyaminoacide de perfluoroalkyle-allyloxy et de perfluoroalkyle-iodopropyloxie substitué.
