N-substituted perfluoroalkylated pyrrolidines of formula (III), where RF, B, Q and q are as defined herein are prepared from diallylamine, a perfluoroalkyl iodide and an amino-reactive compound selected from the group of carboxylic acids, anhydrides, acid chlorides, oxiranes, haloalkanes, isocyanates, ureas and (meth)acrylic compounds. These compounds are useful as specialty surfactants and as oil-proofing agents for paper and textiles. Polymers derived from the (meth)acrylamides are useful to impart water, oil and grease repellency to various substrates. A process for the addition of an Rf-iodide to an olefin which comprises reacting an Rf-iodide with an olefin in the presence of 0.01 to 10 mole % based on the Rf-iodide of a combination an alkali metal dithionite and a water-soluble aldehyde or an adduct of an alkali metal dithionite and a water-soluble aidehyde, where Rf is a monovalent perfluorinated alkyl or alkenyl, linear or branched organic radical having four to twenty fully fluorinated carbon atoms.
