Fluorinated cationic compounds of the formulan whereinn R f 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, R, and R 2 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 R, and R 2 together with the nitrogen atom to which they are attached, represent a 5- or 6-membered heterocyclic radical or R 1 , R 2 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 com- oound of the formulan with a compound of the formulan wherein Y represents halogen. n These compounds are particularly useful as surfactants. |
