Fluorinated-alkyl sulfides represented by [R.sub.f (CH.sub.2).sub.n S].sub.z Q where R.sub.f is fluoroalkyl, n is 2 or 3, z is 1 or 2, and Q is an aryl, alkylaryl, alkyl heterocyclic or heterocyclic radical, are useful as surfactants or as intermediates for the preparation of salt-type, quaternary-salt, or amphoteric surfactants.

Fluorinated heterocyclic sulfides

Flourinated-alkyl sulfides represented by [R.sub.f (CH.sub.2).sub.n S].sub.z Q where R.sub.f is fluoroalkyl, n is 2 or 3, z is 1 or 2, and Q is an aryl, alkylaryl, alkyl heterocyclic or heterocyclic radical, are useful as surfactants or as intermediates for the preparation of salt-type, quaternary-salt, or amphoteric surfactants.

Fluorinated aliphatic sulfides, represented by R.sub.f (CH.sub.2).sub.n S(CH.sub.2).sub.m Q wherein R.sub.f is fluoroalkyl, n is 2 or 3, m is an integer from 2 to 4, Q is --N(R).sub.2 or --N.sup..sym. (R).sub.2 CH.sub.2 COOH X.sup..crclbar. where X is Cl or Br, and R is an alkyl group of 1 to 4 carbon atoms, are particularly effective amphoteric surface-tension depressants or intermediates therefor.
