    Abstract: N-phenyltetrahydrophthalimides of general formula I in which the substituents and the index have the following meanings: R is C1-C4-alkyl; n is 1 or 2; R is hydrogen or fluorine; R is halogen; R is hydrogen or C1-C4-alkyl; R is hydrogen or optionally substituted C1-C8-alkoxycarbonyl, C3-C6- alkenyloxycarbonyl or C3-C6-alkynyloxycarbonyl; X and Y represent oxygen or sulphur; A represents optionally substituted C2-C3-alkylene, where R does not represent hydrogen when X and Y denote oxygen, processes for their preparation, and herbicidal compositions containing them.

    Abstract: N-(Phenyl)-tetrahydroindazole derivatives of the general formula Ia and Ib Ia Ib where R1 is halogen; R2 is C1-C6-alkoxycarbonyl-C3-C5-alkenyl or C1-C3-alkyl which is substituted in the 1- or 2-position by C1-C6-alkoxycarbonyl or a 5- or 6-membered saturated or monounsaturated heterocycle which contains one oxygen or sulfur as heteroatom and can be substituted by from one to four C1-C4-alkyls, and R3 is C2-C7-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C1-C6-alkoxycarbonyl-C3-C5-alkenyl of C1-C3-alkyl which is substituted in the 1- or 2-position by C1-C6-alkoxycarbonyl or a 5- or 6-membered saturated or monounsaturated heterocycle which contains one oxygen or sulfur as heteroatom and can be substituted by from one to four C1-C4-alkyls, their manufacture and their use.

    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.
