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: Prepn. of olefinic cpds. of formula (I) comprises: (a) reaction of a phosphonium salt of formula (V) dissolved n a 1-6C alcohol, with a base and elemental bromine to give a Br-contg. phsophonium slat of formula (III) or a Br-contg. phsophorous of formula (IV); and (b) reaction of a ketone of formula (II) with (III) and a base or with (IV), in a solvent. R1 = an organic gp; R2 = an orgnaic gp. or H; A = COR3, COOR3, CONR3R4 or CN; R3, R4 = an organic gp; X = an anion of a strong acid. The prepn. of (IV) in a 1-6C alcohol is claimed per use. USE/ADVANTAGE - Some +-bromo-substd. cinnamic acid derivs. or vinyl ketones prepd. by this process, e.g. N-(3-(methyl-+-bromo acrylate)-4-chlorophenyl) -3,4,5,6-tetrahydronaphthalimide (Ia) are herbicidally active or are intermediates in herbicide prepn. Previous prepns. of (III) and (IV) took place in solvents, e.g. C6H6, CH3COOH, which are unsuited to Wittig-style reactions or are toxic.
