Zusammenfassung:Novel R-enantiomers of phenoxypropionic acid derivatives of the formula in which Z is nitrogen or the group -CR in which R is hydrogen or halogen, X is oxygen or sulphur, R is alkyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted bicycloalkyl or optionally substituted bicycloalkenyl having in each case at least one asymmetrically substituted carbon atom, R is hydrogen, cyano or nitro, R and R are identical or different and are hydrogen or halogen and R is hydrogen, halogen or trihalogenomethyl, several processes for preparing the novel substances, and their use as herbicides.
