Description

The invention relates to new substituted 3-aryl-pyrrolidine-2,4-dione derivatives, to a plurality of processes for their preparation, and to their use as insecticides, acaricides and herbicides.

3-Acyl-pyrrolidine-2,4-diones have previously been described as having pharmaceutical properties (S. Suzuki et al Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenyl-pyrrolidine-2,4-diones were synthesised by R. Schmierer and H. Mildenberger,Liebigs Ann. Chem. 1985 1095. A biological activity of these compounds has not been described.

EP-A 0,262,399 discloses compounds (3-aryl-pyrrolidine-2,4-diones) which have a similar structure but which were not known as having a herbicidal, insecticidal or acaricidal action.

DE-A 3,525,109 discloses 1 H-3-arylpyrrolidine-2,4-diones which have a similar structure and which are used as intermediates for the syntheses of dyestuffs.

New substituted 3-aryl-pyrrolidine-2,4-dione derivatives have now been found which are represented by the formula (I) ##STR3## in which X represents alkyl, halogen or alkoxy,

Y represents hydrogen, alkyl, halogen, alkoxy or halogenoalkyl, Z represents alkyl, halogen or alkoxy, n represents a number from 0-3, A represents hydrogen, or represents alkyl, alkoxyalkyl or alkylthioalkyl, each of which is optionally substituted by halogen, cycloalkyl which is optionally interrupted by hetero atoms, or represents aryl, arylalkyl or hetaryl, each of which is optionally substituted by halogen, alkyl, halogenoalkyl, alkoxy or nitro, B represents hydrogen, alkyl or alkoxyalkyl, or in which A and B together with the carbon atom to which they are bonded forman optionally substituted saturated or unsaturated cycle which can be interrupted by oxygen and/or sulphur, R represents the groups ##STR4## in which L and M represent oxygen or sulphur, and L and M do not simultaneously represent oxygen, R.sup.1, R.sup.2 and R.sup.3 independently of each other represent alkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkenylthio, alkinylthio and cycloalkylthio, each of which is optionally substituted by halogen, and represent in each case optionally substituted phenyl, benzyl, phenoxy or phenylthio, R.sup.4 and R.sup.5 independently of each other represent hydrogen, or represent alkyl, alkenyl, alkoxy or alkoxyalkyl, each of which is optionally substituted by halogen, or represent optionally substituted phenyl or optionally substituted benzyl, or R.sup.4 and R.sup.5 together represent an alkenyl radical which is optionally interrupted by oxygen, R.sup.6 represents alkyl which is optionally substituted by halogen and which can be interrupted by oxygen, or represents phenyl which is optionally substituted by halogen, halogenoalkyl or alkoxy, or represents benzyl which is optionally substituted by halogen, halogenoalkyl, alkyl and alkoxy, or represents alkenyl or alkinyl, and the pure enantiomeric forms of compounds of the formula (I).

Taking into account the various meanings (a), (b), (c) and (d) of group R of the general formula (I), the following main structures (Ia) to (Id) result: ##STR5## in which A, B, L, M, X, Y, Z.sub.n, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 have the abovementioned meanings.

Furthermore, it has been found that 3-aryl-pyrrolidone-2,4-dione derivatives of the formula (Ia) ##STR6## in which A, B, L, X, Y, Z, R.sup.1, R.sup.2 and n have the abovementioned meaning are obtained when

A) 3-aryl-pyrrolidine-2,4-diones of the formula (II) or the enols thereof ##STR7## in which A, B, X, Y, Z and n have the abovementioned meaning are reacted with phosphorus compounds of the general formula (III) ##STR8## in which L, R.sup.1 and R.sup.2 have the abovementioned meaning and Hal represents halogen, in particular chlorine and bromine, if appropriate in the presence of a diluent, if appropriate in the presence of an acid-binding agent and if appropriate in the presence of a phase-transfer catalyst. B) Furthermore, it has been found that compounds of the formula (Ib) ##STR9## in which A, B, X, Y, Z, R.sup.3 and n have the abovementioned meaning are obtained when compounds of the formula (II) ##STR10## in which A, B, X, Y, Z and n have the abovementioned meaning are reacted with sulphonyl chlorides of the general formula (IV) R.sup.3 --SO.sub.2 --Cl (IV) in which R.sup.3 has the abovementioned meaning, if appropriate in the presence of a diluent and if appropriate in the presence of an acid-binding agent. C) Furthermore, it has been found that compounds of the formula (Ic) ##STR11## in which A, B, L, X, Y, Z, R.sup.4, R.sup.5 and n have the abovementioned meaning, are obtained when compounds of the formula (II) ##STR12## in which A, B, X, Y, Z and n have the abovementioned meaning are either .alpha.) reacted with isocyanates of the general formula (V) R.sup.4 --N.dbd.C.dbd.O (V) in which R.sup.4 has the abovementioned meaning, if appropriate in the presence of a diluent and if appropriate in the presence of a catalyst, or are .beta.) reacted with carbamic acid chlorides or thiocarbamic acid chlorides of the general formula (VI) ##STR13## in which L, R.sup.4 and R.sup.5 have the abovementioned meaning, if appropriate in the presence of a diluent and if appropriate in the presence of an acid-binding agent. D) Furthermore, it has been found that compounds of the formula (Id) ##STR14## in which A, B, L, M, R.sup.6 X, Y, Z, and n have the abovementioned meaning, are obtained when compounds of the formula (II) ##STR15## in which A, B, X, Y, Z and n have the abovementioned meaning .alpha.) are reacted with chloromonothioformic esters, chloroformic thioesters or chlorodithioformic esters of the general formula VII ##STR16## in which L, M and R.sup.6 have the abovementioned meaning, if appropriate in the presence of a diluent and if appropriate in the presence of an acid-binding agent, or .beta.) are reacted with carbon disulphide and subsequently with alkyl halides of the general formula VIII R.sup.6 -Hal (VIII) in which R.sup.6 has the abovementioned meaning and Hal represents chlorine, bromine or iodine.

The active compounds according to the invention are distinguished by a high insecticidal and acaricidal activity.

They can be employed particularly successfully against insects which are harmful to plants, such as, for example, against the larvae of the mustard beetle (Phaedon cochleariae) or against the larvae of the green rice cicada (Nephotettix cinciteps) or against mites which are harmful to plants such as, for example, against the common spider mite or the greenhouse red spider mite (Tetranychus urticae).

The active compounds according to the invention are not only active against plant, hygiene and stored product pests, but also, in the veterinary medicine sector, against animal parasites (ectoparasites and endoparasites) such as scaly ticks, argasidae, scab mites, trombidae, flies (biting and sucking), parasitic fly larvae, lice, hair lice, bird lice, fleas and endoparasitically living worms.

They are active against normally-sensitive and resistant species and strains and against all parasitising and non-parasitising development stages of the ecto- and endoparasites.

The active compounds according to the invention can furthermore be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum. Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita. Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera. Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, on lawns, turf and pasture-land, and for the selective combating of weeds in annual cultures.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, as well as water.

As solid carriers there are suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quarts, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionogenic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumen hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dye-stuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

For combating weeds, the active compounds according to the invention, as such or in the form of their formulations, can also be used as mixtures with known herbicides, finished formulations or tank mixes being possible.

Mixtures with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil structure, are also possible.

The active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomising or scattering.

The active compounds according to the invention can be applied either before or after emergence of the plants. They can also be incorporated into the soil before sowing.

The amount of active compound used can vary within a substantial range. It depends essentially on the nature of the desired effect. In general, the amounts used are between 0.01 and 10 kg of active compound per hectare of soil surface, preferably between 0.05 and 5 kg per ha.

The preparation and use of the active compounds according to the invention can be seen from the following examples.
