N-Substituted perfluoroalkanesulfonamides of the formula: ##STR1## WHEREIN R.sub.f is a 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.

Stunting plant growth with N-substituted perfluoroalkanesulfonamides

A thin layer chromatographic plate housing a substrate and bonded there to a layer of discrete, spherical inorganic metal oxide particles bonded to the substrate by an inorganic metal oxide binder the particles and binder being SrO.sub.2, TiO.sub.2, ZrO.sub.2, or Al.sub.2 O.sub.3.

N-substituted perfluoroalkanesulfonamides as herbicides

Acyl halides, esters, amides, hydrazides and salts as well as the acid form derived from aromatic acids substituted by polyfluoroalkoxy groups. These compounds are valuable as synthetic intermediates in the preparation of physiologically active compounds.
