    Abstract: The invention concerns the preparation of 3-(3,4,5,6-tetrahydrophthalimido)cinnamic acid esters of formula (I) (R = H, halogen; R , R = halogen; R = C-organic rest; R = H, CH3) by the reduction of 3-nitrocinnamic acid esters of formula (II) with hydrogen in the presence of a catalyst and the condensation of the 3-aminocinnamic acid esters obtained of formula (III) with a 3,4,5,6-tetrahydrophthalic acid anhydride of formula (IV). 3-(3,4,5,6-tetrahydrophthalimido)cinnamic acid esters of formula (I) are useful active agents in the plant-protection field.

    Abstract: The invention relates to novel pyridine derivatives, processes for their preparation and their use for the control of undesired plant growth. The pyridine derivatives have the formula in which R 1 is alkylideneaminoxy which is unsubstituted or mono- or disubstituted by alkoxy, alkylthio or phenyl, cycloalkylideneaminoxy which is unsubstituted or mono- or disubstituted by alkyl, succinyliminoxy, or azolyl which is unsubstituted or mono- or disubstituted by alkyl or halogen, R and R are alkyl, haloalkyl, alkoxy, haloalkoxy or alkylthio, R is hydrogen, halogen, alkyl, haloalkyl or alkoxy and Z is nitrogen or the methine group.
