It is also possible to admix other known active compounds, such as herbicides, fertilizers and growth regulators.

[0251] When used as insecticides, the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds according to the invention, without it being necessary for the synergistic agent added to be active itself.

[0252] The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

[0253] The compounds are employed in a customary manner appropriate for the use forms.

[0254] When used against hygiene pests and pests of stored products, the active compound is distinguished by an excellent residual action on wood and clay as well as a good stability to alkali on limed substrates.

[0255] As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.

[0256] Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having specific properties (“traits”) which can be obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. This can be varieties, bio- and genotypes.

[0257] Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions to be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought.or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.

[0258] The preferred transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful properties (“traits,”) to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapevines), and particular emphasis is given to maize, soya beans, potatoes, cotton and oilseed rape. Traits that are emphasized are in particular increased defence of the plants against insects by toxins formed in the plants, in particular those formed by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2,Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defence of plants to fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexius, elicitous and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS(® (tolerance to sulphonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars having these or still to be developed genetic traits, which plants will be developed and/or marketed in the future.

[0259] The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the general formula (I) or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or the mixtures specifically mentioned in the present text.

[0260] The active compounds according to the invention act not only against plant, hygiene and stored product pests, but also in the veterinary medicine sector against animal parasites (ectoparasites), such as hard ticks, soft ticks, mange mites, leaf mites, flies (biting and licking), parasitic fly larvae, lice, hair lice, feather lice and fleas. These parasites include: From the order of the Anoplurida, for example, Haematopinus spp., Linognathus spp., Pediculus spp., Phtirus spp. and Solenopotes spp.

[0264] From the order of the Heteropterida, for example, Cimex spp., Triatoma spp., Rhodnius spp. and Panstrongylus spp.

[0265] From the order of the Blattarida, for example, Blatta orientalis, Periplaneta americana, Blattella germanica and Supella spp.

[0266] From the subclass of the Acaria (Acarida) and the orders of the Meta- and Mesostigmata, for example, Argas spp., Ornithodorus spp., Otobius spp., Ixodes spp., Amblyomma spp., Boophilus spp., Dermacentor spp., Haemophysalis spp., Hyalomma spp., Rhipicephalus spp., Dermanyssus spp., Raillietia spp., Pneumonyssus spp., Sternostoma spp. and Varroa spp.

[0267] From the order of the Actinedida (Prostigmata) und Acaridida (Astigmata), for example, Acarapis spp., Cheyletiella spp., Ornithocheyletia spp., Myobia spp., Psorergates spp., Demodex spp., Trombicula spp., Listrophorus spp., Acarus spp., Tyrophagus spp., Caloglyphus spp., Hypodectes spp., Pterolichus spp; Psoroptes spp., Chorioptes spp., Otodectes spp., Sarcoptes spp., Notoedres spp., Knemidocoptes spp., Cytodites spp. and Laminosioptes spp.

[0268] They have, for example, excellent activity against the development stages of ticks such as, for example, Amblyomma hebraeum and against parasitic flies such as, for example, Lucilia cuprina.

[0269] The active compounds of the formula (I) according to the invention are also suitable for controlling arthropods which infest agricultural productive livestock, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese and bees, other pets, such as, for example, dogs, cats, caged birds and aquarium fish, and also so-called test animals, such as, for example, hamsters, guinea pigs, rats and mice. By controlling these arthropods, cases of death and reduction in productivity (for meat, milk, wool, hides, eggs, honey etc.) should be diminished, so that more economic and easier animal husbandry is possible by use of the active compounds according to the invention.

[0270] The active compounds according to the invention are used in the veterinary sector in a known manner by enteral administration in the form of, for example, tablets, capsules, potions, drenches, granules, pastes, boluses, the feed-through process and suppositories, by parenteral administration, such as, for example, by injection (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal use in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing and powdering, and also with the aid of moulded articles containing the active compound, such as collars, ear marks, tail marks, limb bands, halters, marking devices and the like.

[0271] When used for cattle, poultry, pets and the like, the active compounds of the formula (I) according to the invention can be used as formulations (for example powders, emulsions, free-flowing compositions), which comprise the active compounds according to the invention in an amount of 1 to 80% by weight, directly or after 100 to 10 000-fold dilution, or they can be used as a chemical bath.

[0272] It has furthermore been found that the compounds according to the invention have a strong insecticidal action against insects which destroy industrial materials.

[0273] The following insects may be mentioned as examples and as preferred - but without a limitation:

[0278] Industrial materials in the present connection are to be understood as meaning nonliving materials, such as, preferably, plastics, adhesives, sizes, papers and cards, leather, wood and processed wood products and coating compositions.

[0279] Wood and processed wood products are materials to be protected, especially preferably, from insect infestation.

[0280] Wood and processed wood products which can be protected by the agents according to the invention or mixtures comprising these are to be understood as meaning, for example:

[0281] building timber, wooden beams, railway sleepers, bridge components, boat jetties, wooden vehicles, boxes, pallets, containers, telegraph poles, wood panelling, wooden window frames and doors, plywood, chipboard, joinery or wooden products which are used-quite generally in house-building or in building joinery.

[0282] The active compounds according to the invention can be used as such, in the form of concentrates or in generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

[0283] The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds according to the invention with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, a water repellent, if appropriate siccatives and UV stabilizers and if appropriate dyestuffs and pigments, and also other processing auxiliaries.

[0285] The amount of the compositions or concentrates employed depends on the nature and occurrence of the insects and on the medium. The optimum amount employed can be determined for the use in each case by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be preserved.

[0286] Solvents and/or diluents which are used are an organic chemical solvent or solvent mixture and/or an oily or oil-like organic chemical solvent or solvent mixture of low volatility and/or a polar organic chemical solvent or solvent mixture and/or water, and if appropriate an emulsifier and/or wetting agent.

[0290] The organic oily or oil-like solvents of low volatility which have an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., can be replaced in part by organic chemical solvents of high or medium volatility, provided that the solvent mixture likewise has an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

[0291] According to a preferred embodiment, some of the organic chemical solvent or solvent mixture is replaced by an aliphatic polar organic chemical solvent or solvent mixture. Aliphatic organic chemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

[0292] Organic chemical binders which are used in the context of the present invention are the synthetic resins and/or binding drying oils which are known per se, are water-dilutable and/or are soluble or dispersible or emulsifiable in the organic chemical solvents employed, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-coumarone resin, silicone resin, drying. vegetable oils and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

[0293] The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. Dyestuffs, pigments, water-repelling agents, odour correctants and inhibitors or anticorrosive agents and.the like which are known per se can additionally be employed.

[0294] It is preferred according to the invention for the composition or concentrate to comprise, as the organic chemical binder, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

[0295] All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

[0296] The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic. acid esters.

[0297] Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether or ketones, such as benzophenone or ethylenebenzophenone.

[0298] Possible solvents or diluents are, in particular, also water, if appropriate as a mixture with one or more of the abovementioned organic chemical solvents or diluents, emulsifiers and dispersing agents.

[0299] Particularly effective preservation of wood is achieved by impregnation processes on a large industrial scale, for example vacuum, double vacuum or pressure processes.

[0300] The ready-to-use compositions can also comprise other insecticides, if appropriate, and also one or more fungicides, if appropriate.

[0301] Possible additional mixing partners are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in this document are an explicit constituent of the present application.

[0302] Especially preferred mixing partners which may be mentioned are insecticides, such as chlorpyriphos, phoxim, silafluofm, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron, transfluthrin, thiacloprid, methoxyfenozide and triflumuron, and also fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorfluanid, tolylfluanid, 3-iodo-2propinyl-butyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

[0303] The compounds according to the invention can at the same time be employed for protecting objects which come into contact with saltwater or brackish water, such as hulls, screens, nets, buildings, moorings and signalling systems, against fouling.

[0304] Fouling by sessile Oligochaeta, such as Serpulidae, and by shells and species from the Ledamorpha group (goose barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (acorn barnacles), such as Balanus or Pollicipes species, increases the frictional drag of ships and, as a consequence, leads to a marked increase in operation costs owing to higher energy consumption and additionally frequent residence in the dry dock.

[0305] Apart from fouling by algae, for example Ectocarpus sp. and Ceramium sp., fouling by sessile Entomostraka groups, which come under the generic term Cirripedia (cirriped crustaceans), is of particular importance.

[0306] Surprisingly, it has now been found that the compounds according to the invention, alone or in combination with other active compounds, have an outstanding antifouling action.

They can be employed alone or in combination with other active compounds and auxiliaries in domestic insecticide products for controlling these pests.

[0376] Under argon, 2-(4-bromophenyl)-5-(2,6-difluorophenyl)-3,4-dihydro-2H-pyrrole (0.84 g, 2.50 mmol), bis(pinacolato)diboron (0.76 g, 3.0 mmol), potassium acetate (0.74 g, 7.50 mmol) and PdCl2dppf (60 mg, 0.075 mmol) are heated in dimethylfonnamide (15 ml) are heated at 80° C. for 2 hours. After cooling, 2-ethyl-5(4-bromo-phenyl)-1(2)H-tetrazole (VII-3) (0.76 g, 3.0 mmol), PdCl2dppf (60 mg, 0.075 mmol) and sodium carbonate solution (7.5 ml, 2M in water) are added, and the mixture is stirred at 80° C. for 16 hours. The reaction mixture is poured into water (60 ml) and extracted with ethyl acetate (2×50 ml). The combined organic phases are dried over sodium sulphate and filtered. Florisil (6.0 g) is added, and the solvent is removed under reduced pressure. The crude product (which is absorbed on Florisil) is purified by silica gel chromatography (mobile phase: n-hexane/ethyl acetate 9:1→3:1).

[0377] This gives 0.66 g (62% of theory) of 5-{4′-[5-(2,6-difluorophenyl)-3,4-dihydro-2Hpyrrol-2-yl]-1,1′-biphenyl-4-yl}-2-ethyl-2H-tetrazole. HPLC: logP (pH 2.3)=3.21 (91.98%) NMR (CD3CN): δ=1.64 (3H, t), 1.85 (1H, m), 2.65 (1H, m), 3.08 (2H, m), 4.71 (2H, q), 5.34 (1H, m), 7.09 (2H, m), 7.47 (3H, m), 7.72 (2H, d), 7.82 (2H, d), 8.18 (2H, d) ppm.

[0378] Preparation of Starting Materials of the Formula (VII)

Example (VII-1)

[0379]

[0380] A mixture of 20 g (0.089 mol) of 5-(4-bromo-phenyl)-1(2)H-tetrazole, 20 ml of tertbutanol, 5.4 ml of concentrated sulphuric acid and 100 ml of trifluoroacetic acid is stirred at room temperature for 18 hours. The trifluoroacetic acid is then distilled off under reduced pressure, the residue is partitioned between ethyl acetate and concentrated sodium bicarbonate solution and the organic phase is separated off and dried over sodium sulphate. The solvent is then removed under reduced pressure.

[0381] This gives 18.4 g (74% of theory) of 2-tert-butyl-5-(4-bromo-phenyl)-1(2)H-tetrazole. HPLC: logP (pH 2.3)=4.23

Example (VII-2)

[0382]

[0383] A mixture of 5.6 g (0.025 mol) of 5-(4-bromo-phenyl)-1(2)H-tetrazole, 2.8 g (0.03 mol) of chloromethyl ethyl ether, 4.1 g (0.03 mol) of potassium carbonate and 150 ml of acetonitrile is stirred at 60° C. for 18 hours. The solvent is then distilled off under reduced pressure, the residue is partitioned between ethyl acetate and water and the organic phase is separated off and dried over sodium sulphate. The solvent is distilled off, and the residue is then purified by silica gel chromatography (mobile phase: methylene chloride).

[0384] This gives 3 g (43% of theory) of 2-ethoxymethyl-5-(4-bromo-phcnyl)-1(2)H tetrazole as a colourless powder. HPLC: logP (pH2.3)=3.42

Example (VII-3)

[0385]

[0386] Analogously to Example (VII-2), reaction of 5-(4-bromo-phenyl)-1(2)H-tetrazole with ethyl iodide gives the compound 2-ethyl-5-(4-bromo-phenyl)-1(2)H-tetrazole.

[0387] HPLC: logP (pH 2.3)=3.20

[0388] The stated logP values were determined in accordance with EEC Directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) using a reversed-phase column (C 18). Temperature: 43° C.

[0389] In the acidic range, the determination was carried out at pH 2.3 using the mobile phases 0.1% aqueous phosphoric acid and acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile.

[0390] In the neutral range, the determination was carried out at pH 7.5 using the mobile phases 0.01 molar aqueous phosphate buffer solution and acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile.

[0391] Calibration was carried out using unbranched alkan-2-ones (having 3 to 16 carbon atoms) with known logP values (determination of the logP values by the retention times using linear interpolation between two successive alkanones).

[0392] The lambda max values were determined in the maxima of the chromatographic signals using the UV spectra from 200 nm to 400 nm.
