  • N-substituted perfluoroalkanesulfonamides as herbicides
    Patent number: 4076519
    Abstract: N-Substituted perfluoroalkanesulfonamides of the formula: ##STR1## WHEREIN R.sub.f is perfluoroalkyl group containing one to four carbon atoms, each Y is a non-cyclic group which can contain only carbon, hydrogen, oxygen, sulfur, nitrogen and halogen and m is 1-5, provided that all of the Y groups together contain not more than about twenty carbon atoms and that at least one of the Y groups contains a heteroatom selected from oxygen, sulfur, nitrogen and halogen. Also included are salts of these compounds, compositions containing the compounds of the present invention and processes for their preparation and use. The compounds are active as herbicides and plant growth modifiers.
