Abstract
NEW MATERIAL:Pentenoic acid derivative of formula I (R is 4-trifluoromethylphenyl or 3,5-dichloro-2-phridyl; R' is cyanoethyl, dialkylaminoethyl, alkoxyethoxyethyl, benzyl, halobenzyl, methylbenzyl, pyridylmethyl, etc.).
USE: Herbicide having an excellent selectivity, a strong herbicidal activity to Gramineas weeds and a high safety to broadleaved crops. Extremely stable to the environmental factors, e.g. weather conditions, soil conditions, etc. Excellent long-lasting activity. Highly effective for the stem and leaf treatment.
PROCESS: The objective compound of formula I is obtained by the reaction of a compound of formula II with a compound of formula III (X is halogen) in the presence of a base.
