Herbicidal 5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl-oxyacetanilides

Abstract

The invention relates to novel 5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl-oxyacetanilides of the general formula (I) in which n represents the number 0, 1, 2 or 3, R represents straight-chain or branched alkyl having 1 to 4 carbon atoms, and X represents nitro, cyano, halogen or represents in each case optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl, alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl having in each case 1 to 4 carbon atoms, except for the compounds N-methyl-5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl-oxyacetanilide, N-ethyl-5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl-oxyacetanilide, 4-chloro-N-methyl-(5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl)-oxyacetanilide and 3-trifluoromethyl-N-methyl-(5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl)-oxyacetanilide, N-i-propyl-5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl-oxyacetanilide, and 4-fluoro-N-methyl-(5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl)-oxyacetanilide and 4-fluoro-N-ethyl-(5-chlorodifluoromethyl-1,3,4-thiadiazol-2-yl)-oxyacetanilide, and to a process for their preparation and to their use as herbicides.
