Zusammenfassung:1. Process for the preparation of benzimidazolyl-, benzoxazolyl- and benzthiazolyl-oxyphenoxypropionic acid derivatives of the formula I see diagramm : EP0157225,P9,F2 wherein X denotes oxygen or sulphur or a group of the formula = N-alkyl (C1 -C4 ), R denotes halogen or CF3 , n denotes the numbers 0 to 3 and R**1 denotes (C1 -C12 )-alkyl which can be substituted by (C1 -C6 )-alkoxy, (C1 -C6 )-alkylthio, (C1 -C6 )-alkoxy-(C2 -C4 )-alkoxy or methoxyethoxyethoxy ; C5 -cycloalkyl or C6 -cycloalkyl ; or (C1 -C4 )-alkoxycarbonyl-(C1 or C2 )-alkyl, by reacting compounds of the formula II see diagramm : EP0157225,P9,F3 in which X, R and n have the meaning indicated above, with compounds of the formula III see diagramm : EP0157225,P9,F4 in which Y is chlorine and R**1 has the meaning indicated above, characterised in that catalytic amounts of metal iodide and/or 2-iodopropionic acid esters of the formula III in which Y = I as well as bases are added to the reaction mixtures at temperatures of from 50 to 250 degrees C in at least stoichiometric amounts.
