Abstract
Abstract The perfluoroalkylthio amidoalkyl amine or ammonium compounds having the structures ##STR1## where R f is a perfluoroalkyl, R 1 is alkylene or alkylene oxy or amino alkylene, R 2 is hydrogen or alkyl, R 3 and R 4 are independently alkyl or together form a heterocyclic ring, R 5 is hydrogen or alkyl, R 6 is hydrogen, oxide, alkyl or substituted alkyl, E is alkylene or polyoxyalkylene, X is an anion, y is 1 or 2 and z is 0 or 1, which can be prepared by the base-catalyzed addition of a perfluoroalkylthiol to an α,β-unsaturated amide. These compounds are useful as surfactants.
