| 摘要 |
The instant invention relates to fluorinated cationic compounds of the formula <IMAGE> (I) wherein Rf is a perfluoroalkyl or perfluoroalkoxy-perfluoroalkyl group; R1 is alkylene optionally interrupted by -O-, -S+13, -SO2-, -SO2NR'-, -CO2-, -NR'-, or -CONR'- where R' is hydrogen or lower alkyl; m is 0, 1 or 2; R2 is linear or branched alkylene; R3, R4, and R5 independently of one another represent alkyl or arylalkyl groups which are unsubstituted or substituted by hydroxyl, lower alkoxy, halogen, cyano or by polyalkyleneoxy, or R3 and R4 together with the nitrogen atom to which they are attached represent a 5- or 6-membered heterocyclic radical or R3, R4 and R5 together with nitrogen atom that links them represent a substituted or unsubstituted pyridine ring; and A(-) represents the anion of an organic or inorganic acid; and their particular use as surfactants.
