Novel derivatives of phenoxypropionic acid, of the formula <IMAGE> in which R<1> represents radicals of the formulae <IMAGE> where X<1> represents hydrogen or halogen, X<2> represents halogen or trifluoromethyl, X<3> represents halogen or trifluoromethyl, X<4> represents hydrogen or halogen and X<5> represents hydrogen or halogen, Y represents oxygen or the radical SOm, where m represents 0, 1 or 2, and R<2> and R<3> independently of one another represent hydrogen, halogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, alkylthio having 1 to 4 carbon atoms, nitro, cyano or alkoxycarbonyl having 1 to 4 carbon atoms in the alkoxy group, a plurality of processes for the preparation of the novel substances, and their use as herbicides. Novel intermediates and their preparation. |
