ABSTRACT:

The invention relates to new phenyl-substituted cyclic ketoenols, a plurality of processes and intermediates for their preparation and their use as pesticides and herbicides.
It has already been disclosed that certain phenyl-substituted cyclic ketoenols are effective as insecticides, acaricides and/or herbicides.
Pharmaceutical properties of 3-acyl-pyrrolidine-2,4-diones have previously been described (S. Suzuki et al. Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenylpyrrolidine-2,4-diones have been synthesized by R. Schmierer and H. Mildenberger (Liebigs Ann. Chem. 1985, 1095). A biological activity of these compounds has not been described.
EP-A-0262399 and GB-A-2266888 disclose compounds (3-aryl-pyrrolidine-2,4-diones) of similar structure, of which, however, no herbicidal, insecticidal or acaricidal action has been disclosed. Unsubstituted, bicyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A-355599 and EP-A-415211) and substituted monocyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A-377893 and EP-A-442077) with herbicidal, insecticidal or acaricidal action are known.
Polycyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-442073) and 1H-arylpyrrolidine-dione derivatives (EP-A-456063, EP-A-521334, EP-A-596298, EP-A-613884, DE 4440594, EP-A-613885, WO 94/01997 and WO 95/01358) are furthermore known.
It is known that certain substituted &Dgr;
3
-dihydrofuran-2-one derivatives have herbicidal properties (cf. DE-A-4014420). The synthesis of the tetronic acid derivatives used as starting compounds (e.g. 3-(2-methyl-phenyl)-4-hydroxy-5-(4-fluorophenyl)-&Dgr;
3
-dihydrofuran-2-one) is likewise described in DE-A-4014420. Compounds of similar structure without details of an insecticidal and/or acaricidal activity are known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1, 1985, (8) 1567-76. Furthermore, 3-aryl-&Dgr;
3
-dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties are disclosed in EP-A-528156, but the action described there is not always adequate. 3-Aryl-4-hydroxy-&Dgr;
3
-dihydrofuranone derivatives are disclosed in EP-A-647637. Thiotetronic acids are disclosed in WO 95/26345.
The literature further discloses certain 3H-pyrazol-3-one derivatives, 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} [lacuna] 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). A biological action of these compounds, however, is not described.
It is furthermore known that the trisodium salt of 4,4′,4″-(5-hydroxy-3-oxo-1H-pyrazole-1,2,4(3H)-triyl)-tris-benzenesulphonic acid has pharmacological properties (cf. Farmakol. Toksikol. (Moscow), 38(2), 180-186, 1976). Its use in plant protection, however, is not known.
In addition, EP-A-508126 and WO 92/16510 describe 4-arylpyrazolidine-3,5-dione derivatives having herbicidal, acaricidal and insecticidal properties.
Certain phenyl-pyrone derivatives unsubstituted in the phenyl ring have already been disclosed (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 utility for these compounds as pesticides not being indicated. Phenyl-pyrone derivatives substituted in the phenyl ring and having herbicidal, acaricidal and insecticidal properties are described in EP-A-588137.
Certain 5-phenyl-1,3-thiazine derivatives unsubstituted in the phenyl ring have already been described (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 application as pesticides not being indicated for these compounds. 5-Phenyl-1,3-thiazine derivatives substituted in the phenyl ring and having herbicidal, acaricidal and insecticidal action are described in WO 94/14785.
The activity and spectrum of action of these compounds, however, is not always completely satisfactory, in particular at low application rates and concentrations.
New compounds of the formula (I)
have now been found,

Z represents halogen or alkyl,
with the proviso that one of the radicals Y and Z always represents halogen and the other alkyl,

The compounds of the formula (I) can also be present, depending on the nature of the substituents, as geometric and/or optical isomers or isomer mixtures of differing composition which, if appropriate, can be separated in a customary manner. Both the pure isomers and the isomer mixtures, their preparation and use, and compositions containing these are a subject of the present invention. In the following, for the sake of simplicity, however, compounds of the formula (I) are always referred to, although both the pure compounds and, if appropriate, mixtures of different proportions of isomeric compounds are intended.
