Abstract

NEW MATERIAL:α-Phenoxypropionic acid derivatives expressed by formula I: (X is 4-trifluoromethylphenyl or 3, 5-dichloro-2-pyridyl group).
EXAMPLE: 2-[4-(3, 5-Dichloropyridyl-2-oxy)phenoxy] propionic acid-(2-N-acetylamino) ethyl ester.
USE: Selective herbicides having improved rapid-acting selective herbicidal actions on the Gramineal weeds, e.g. green panicum, foxtail, etc. and almost non-toxic to broadleaf crops, e.g. leguminous plants, beats, etc.
PROCESS: α-Phenoxypropionic acid chlorides of formula II are reacted with 2- acetaminoethanol, etc. in the presence of an acid binder, e.g. pyridine, etc. at- 5W0°C to give the desired compounds of formula I
