DETAILED DESCRIPTION OF THE INVENTION
EP-A-0 262 399 and GB-A-2 266 888 disclose compounds of a similar structure (3-aryl-pyrrolidine-2,4-diones) of which, however, no herbicidal, insecticidal or acaricidal activity has become known. Unsubstituted bicyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A-355 599 and EP-415 211) and substituted monocyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A-377 893 and EP-442 077) having herbicidal, insecticidal or acaricidal activity are known.
Also known are polycyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-442 073) and 1H-arylpyrrolidine-dione derivatives (EP-456 063, EP-521 334, EP-596 298, EP-613 884, EP-613 885, WO 95/01997, WO 95/26954, WO 95/20572, EP-A-0 668 267, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243 and WO 97/36 868, WO 98/05 638, WO 98/06721, WO 98/25928, WO 99/16748, WO 99/24437).
It is known that certain substituted &Dgr;
3
-dihydrofuran-2-one derivatives have herbicidal properties (cf. DE-A-4 014 420). The synthesis of the tetronic acid derivatives used as starting materials, (such as, for example, 3-(2-methyl-phenyl)-4-hydroxy-5-(4-fluorophenyl)-&Dgr;
3
-dihydrofuran-2-one) is likewise described in DE-A-4 014 420.
Compounds of a simular structure are known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1, 1985, (8) 1567-76 without any insecticidal and/or acaricidal activity being mentioned. Furthermore, 3-aryl-&Dgr;
3
-dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties are known from EP-A-528 156, EP-A-0 647 637, WO 95/26 345, WO 96/20 196, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243 and WO 97/36 868, WO 98/05 638, WO 99/16748, WO 98/25928. 3-Aryl-&Dgr;
3
-dihydrothiophenone-derivatives are likewise known (WO 95/26 345, 96/25 395, WO 97/01 535, WO 97/02 243, WO 97/36 868, WO 98/05 638, WO 98/25928).
Also known from the literature are certain 3H-pyrazol-3-one derivatives, such as, for example, 1,2-diethyl-1,2-dihydro-5-hydroxy-4-phenyl-3H-pyrazol-3-one or {[5-oxo-1,2-diphenyl-4-(p-sulphophenyl)-3-pyrazolin-3-yl]-oxy}, disodium salt, or p-(3-hydroxy-5-oxo-1,2-diphenyl-3-pyrazolin-4-yl)-benzenesulphonic acid (cf. J. Heterocycl. Chem., 25(5), 1301-1305, 1988 or J. Heterocycl. Chem., 25(5), 1307-1310, 1988 or Zh. Obshch. Khim., 34(7), 2397-2402, 1964). However, a biological activity of these compounds is not described.
Furthermore, it is known that the trisodium salt of 4,4′,4″-(5-hydroxy-3-oxo-1H-pyrazol-1,2,4(3H)-triyl)-tris-benzenesulphonic acid has pharmacological properties (cf. Farmakol. Toksikol. (Moscow), 38(2), 180-186, 1976). However, it is not known to be used in crop protection.
Moreover, EP-508 126 and WO 92/16 510, WO 96/21 652 describe 4-aryl-pyrazolidine-3,5-dione derivatives having herbicidal, acaricidal and insecticidal properties. Additionally, 4-arylpyrazolidines have become known, of which fungicidal properties have been described (WO 96/36 229, WO 96/36 615, WO 96/36 616, WO 96/36 633).
Certain phenyl-pyrone derivatives which are unsubstituted in the phenyl ring have already become known (cf A. M. Chirazi, T. Kappe and E. Ziegler, Arch. Pharm. 309, 558 (1976) and K. -H. Boltze and K. Heidenbluth, Chem. Ber. 91, 2849), a possible use of these compounds as pesticides not being mentioned. Phenyl-pyrone derivatives which are substituted in the phenyl ring and have herbicidal, acaricidal and insecticidal properties are described in EP-A-588 137, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/16 436, WO 97/19 941 and WO 97/36 868, WO 98/05 638.
Certain 5-phenyl-1,3-thiazine derivatives which are unsubstituted in the phenyl ring have already become known (cf. E. Ziegler and E. Steiner, Monatsh. 95, 147 (1964), R. Ketcham, T. Kappe and E. Ziegler, J. Heterocycl. Chem. 10, 223 (1973)), a possible use of these compounds as pesticides not being mentioned. 5-Phenyl-1,3-thiazine derivatives which are substituted in the phenyl ring and have herbicidal, acaricidal and insecticidal activity are described in WO 94/14 785, WO 96/02 539, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/02 243, WO 97/36 868.
It is known that certain substituted 2-arylcyclopentanediones have herbicidal and acaricidal properties (cf., for example, U.S. Pat. Nos. 4,283,348; 4,338,122; 4,436,666; 4,526,723; 4,551,547; 4,632,698; WO 96/01 798; WO 96/03 366 and also WO 97/14 667, WO 98/39281). Moreover, compounds of a similar structure are known; 3-hydroxy-5,5-dimethyl-2-phenylcyclopent-2-ene-1-one from the publication Micklefield et al., Tetrahedron, (1992), 7519-26 and the natural product involutine (−)-cis-5-(3,4-dihydroxyphenyl)-3,4-dihydroxy-2-(4-hydroxyphenyl)-cyclopent-2-enone from the publication Edwards et al., J. Chem. Soc. S, (1967), 405-9. An insecticidal or acaricidal activuty has not been described. Moreover, 2-(2,4,6-trimethylphenyl)-1,3-indanedione is known from the publication J. Economic Entomology, 66, (1973), 584 and the Offenlegungsschrift DE-2 361 084, with herbicidal and acaricidal activities being mentioned.
It is known that certain substituted 2-arylcyclohexanediones have herbicidal and acaricidal properties (U.S. Pat. Nos. 4,175,135, 4,209,432, 4,256,657, 4,256,658, 4,256,659, 4,257,858, 4,283,348, 4,303,669, 4,351,666, 4,409,153, 4,436,666, 4,526,723, 4,613,617, 4,659,372, DE-2 813 341, and also Wheeler, T. N., J. Org. Chem. 44, 4906 (1979)).
However, the activity and the activity spectrum of these compounds are, in particular at low application rates and concentrations, not always entirely satisfactory. Furthermore, the compatibility of these compounds with plants is not always satisfactory.
This invention, accordingly, provides novel compounds of the formula (I)
in which
W represents hydrogen, halogen, alkyl, alkoxy, alkenyloxy, halogenoalkyl, halogenoalkoxy, halogenoalkenyloxy, nitro or cyano,
X represents halogen, alkyl, alkoxy, alkenyloxy, alkylthio, alkylsulphinyl, alkylsulphonyl, halogenoalkyl, halogenoalkoxy, halogenoalkenyloxy, nitro, cyano or in each case optionally substituted phenyl, phenoxy, phenylthio, phenylalkoxy or phenylalkylthio,
Y represents in each case optionally substituted cycloalkyl, aryl or hetaryl,
Z represents hydrogen, halogen, alkyl, alkoxy, halogenoalkyl or halogenoalkoxy,
CKE represents one of the groups
 in which
A represents hydrogen, in each case optionally halogen-substituted alkyl, alkenyl, alkoxyalkyl, polyalkoxyalkyl, alkylthioalkyl, saturated or unsaturated, optionally substituted cycloa
