- wherein R.sub.f is monovalent, saturated fluoroalkyl radical having from 1 to 18 carbon atoms; X is a monovalent, nonionic, electron withdrawing radical at least as electron withdrawing as a benzoyl radical selected from the group consisting of a cyano, phenylcarbonyl, alkylcarbonyl, perfluoroalkylcarbonyl of 2 to 18 carbon atoms, phenylsulfonyl, perfluoroalkylsulfonyl of 1-18 carbon atoms, nitro, fluorosulfonyl, or chlorosulfonyl group; R is hydrogen, an alkyl group, or a phenyl group; R' is the same as R with at least one being hydrogen; n is an integer from 0 to 7 depending on Z; n is 1 to 7 when Z is 2-furyl; n is zero when Z is a monovalent unsaturated, conjugated heterocyclic organic radical selected from the group consisting of furyl, thenyl and 1H-pyrrolyl.
- 2. The compound of claim 1 wherein X is SO.sub.2 R'.sub.f wherein R'.sub.f is perfluoroalkyl of 1-18 carbons.
- 3. The compound of claim 2 wherein R'.sub.f and R.sub.f are perfluoromethyl groups.
