Extensive laboratory testing of fluoroaliphatic sulfones (Rf,SO2,R) showed that, in particular, sulfonamide (Rf,SO2,NR1R2) analogs have potential as delayed-action toxicants for control of the red imported fire ant, Solenopsis invicta Buren. Delayed activity was observed when R1 and R2 = H or alkyl with one exception (R1 = H, R2 = t-butyl). Dependent on the double-bond position, unsaturated hydrocarbon substituents gave either fast kill or delayed activity. Monoalcohol substituents showed delayed activity, but diols were inactive. Polyether substituents, either hydrogen or methyl end-capped, showed similar delayed activity. The C8F17 fluorocarbon radical yielded the best activity. Both the fluorocarbon and sulfone groups were essential to the activity of this class of compounds.
