Fluorinated cationic compounds of the formula <CHEM> wherein Rf is perfluoroalkyl or said perfluoroalkyl substituted by perfluoroalkoxy, Q is alkylene, alkylene thioalkylene, alkylene oxyalkylene or alkylene iminoalkylene, wherein the imino group is optionally substituted by alkyl of 1 to 6 carbon atoms, V, R1 and R2 independently of one another represent optionally substituted alkyl, or cycloalkyl, benzyl, phenyl or polyalkyleneoxy of 2 to 20 alkoxy units and alkylene units of 2 to 4 carbon atoms, or R1 and R2 together with the nitrogen atom to which they are attached, represent a 5- or 6-membered heterocyclic radical or R1, R2 and V together with the nitrogen atom which links them, represent a pyridine ring and A<(-)> represents the anion of an organic or inorganic acid which are prepared by reacting a mercaptan compound of the formula Rf-Q-SH with a compound of the formula <CHEM> wherein Y represents halogen. These compounds are particularly useful as surfactants. |
