Claims
- 1. A phenethylacrylamide of the formula I: in which the substituents have the following meanings:X is halogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C8-alkoxy, C1-C4-haloalkoxy and —O—C(Ra,Rb)—C≡C—Rc; Ra,Rb independently of one another are hydrogen and C1-C6-alkyl; Rc is hydrogen, C1-C8-alkyl, C3-C8-cycloalkyl and phenyl which can be substituted by halogen, cyano, nitro CF3, C1-C4-alkyl and/or C1-C4-alkoxy; m is 1 to 4, it being possible for the radicals X to be different if m is greater than 1; n is 1 or 2; it being possible for the radicals Y to be different if n is 2; Y is halogen, nitro, cyano, C1-C4-alkyl, CF3, C1-C4-alkoxy and phenyl, Y being in the 3-, 4- or 3,4-position; R1, R2 independently of one another are hydrogen, halogen, C1-C4alkyl, C1-C4-alkoxy, C1-C4-haloalkoxy and CF3; R3,R4,R5,R6 independently of one another are hydrogen, C1-C4-alkyl and C1-C4-alkoxy or R3 and R4 together form a cyclopropyl ring, it being possible for the C—R5- and C—R6-bonds to be in the E- or Z-position relative to each other; for controlling phytopathogenic fungal pests.
- 2. A phenethylacrylamide of the formula I as claimed in claim 1 wherein R1 and R2 are identical and are Cl, F and CH3.
- 3. A phenethylacrylamide of the formula I as claimed in claim 1 where m is 1 or 2 and X is in the 3-, 4- or 3,4-position.
- 4. A phenethylacrylamide of the formula I as claimed in claim 1 where X is C1-C8-alkoxy and Y is halogen.
- 5. A phenethylacrylamide of the formula I as claimed in claim 1 wherein R3 and R4 are hydrogen.
- 6. A phenethylacrylamide of the formulae:
- 7. A process for the preparation of a compound of claim 2, which comprises α-keto esters of the formula II: where R is C1-C4-alkylwith triphenylphosphine and, if R1 and R2 are chlorine, with CC14, or, if R1 and R2 are fluorine, with sodium difluorochloroacetate, or, if R1 and R2 are methyl, with isopropyltriphenylphosphonium halide under basic conditions to give acrylic esters of the formula III: and hydrolyzing III to give carboxylic acids of the formula IV: and subjecting IV to a condensation reaction with phenethylamines of the formula V: to give compounds of the formula I.
- 8. A composition which is suitable for controlling phytopathogenic harmful fungi, comprising a solid or liquid carrier and a compound of the formula I as claimed in claim 2.
- 9. A method of controlling phytopathogenic harmful fungi, which comprises treating the fungi or the materials, plants, the soil or seed to be protected from fungal infection with an effective amount of a compound of the formula I as claimed in claim 1.
