The compounds according to formula (I) may be prepared according to the following reaction schemes.

Scheme 1A A compound of formula (II) [where R3 is as defined above for a compound of formula (I)] may be prepared by a reaction sequence starting with a crossed-aldol condensation of benzaldehyde with a ketone of formula CH3C (O) R3 [where R3 is as defined above for a compound of formula (I)] in the presence of NaOH or KOH in a solvent (such as water or ethanol) and usually under reflux conditions or alternatively by reaction of benzaldehyde with a Wittig reagent under standard conditions. The resulting a, p-unsaturated ketone of formula (III) [where R3 is as defined above for a compound of formula (I)] :

may then be converted into a compound of formula (IV) [where R3 is as defined above for a compound of formula (I)] : by reacting first with hydrazine hydrate in ethanol under reflux conditions and then heating (in the range 150 to 250°C) in the presence of KOH (distilling off the solvent).

After nitration with HN03/H20 or HN03/acetic anhydride in a cooled vessel (in the range-30°C to 0°C), the resultant o/p-mixture of nitrobenzene of formula (V) [where R3 is as defined above for a compound of formula (I)] : may then be separated and catalytically reduced (Pt/C/H2 or Ra-Ni/H2) in a solvent (such as methanol, ethanol or THF) at room temperature, to produce a crude o/p-mixture of a compound of formula (II), which may be further purified by standard techniques.

Alternatively, a compound of formula (IT) [where R3 is as defined above for a compound of formula (I)] may be prepared by a process as illustrated by the following reaction sequence and which involves a Pd (In-catalysed imination step.

Scheme 1B (Xll) (Xl) A compound of formula (Vm) [where R3 is as defined above for a compound of formula (I)] is added to bromine and methanol at a temperature of 5-10°C, after which triphenylphosphine in a solvent [such as tetrahydrofuran] is added, to produce a compound of formula (IX) [where R3 is as defined above for a compound of formula (I)], which in turn is added to sodium hydride, in a solvent [such as DMSO], and then reacted with 2-bromobenzaldehyde or 2-iodobenzaldehyde to yield a compound of formula (X) [where R3 is as defined above for a compound of formula (I) and Hal is bromo or iodo]. The resultant compound of formula (X) is then mixed with hydrazine hydrate in a solvent [such as ethanol] and heated to reflux, after which potassium hydroxide is added and the resultant reaction mixture is maintained at 200-220°C for several hours. A standard extraction and purification procedure yields a compound of formula (XI) [where R3 is as defined above for a compound of formula (I) and Hal is bromo or iodo] which may then be converted to a compound of formula (In by mixing with benzophenone imine, sodium tertiary butoxide, tris-dibenzylideneacetone- dipalladium (Pddba,), racemic 2,2'-bis (diphenylphosphino)-l, l'-binaphthyl (BINAP) and a solvent [such as benzene or toluene] and heating at reflux temperature, typically for several hours, and adding the resultant [usually crude isolated] imine to a mixture of hydroxylamine hydrochloride, sodium acetate and a solvent [such as methanol]. The resultant mixture is stirred, preferably for about an hour at room temperature, after which

a cis-/trans-mixture of a compound of formula (II) may be extracted and subsequent separation of the cis-and trans-isomers achieved by using flash chromatography.

In the above illustrated Pd-catalysed imination process, instead of the catalyst- ligand-system Pddba,/BINAP, the system palladium diacetate/1, 1'-bis (diphenyl- phosphino) ferrocene (dppf) could be used as an alternative.

Reaction scheme 1B is novel and inventive, particularly the use of a Pd (II)-catalysed imination step. Therefore in a still further aspect the present invention provides a process for preparing a compound of formula (II), where R3 is as defined above, comprising at least one of the steps of reaction scheme 1B ; in particular a step using a Pd (II) catalyst-ligand-system [where the ligand is selected from a suitable sterically demanding phosphine (for example BINAP or dppf)] to react a compound of formula (XI) [where Hal is bromo or iodo; and R3 is as defined above] with benzophenone imine optionally in the presence of a base [such as sodium-tert- butanolate, potassium-tert-butananolate, sodium carbonate, potassium carbonate or cesium carbonate] to produce a compound of formula (XII) [where R3 is as defined above].

Examples of imination reactions with benzophenone imine are provided in the literature (Journal of Organometallic Chemistry, 1999,576, 125-146 and Tetrahedron Lettersl997,38, 6367-6370).

Scheme 2 The synthesis of an amine of formula (IIA) [where R3A is hydrogen or methyl] may be accomplished by a reaction sequence started by a Wittig reaction of o-nitrobenzaldehyde with an ylide [prepared from a cyclopropylmethlytriphenylphosphonium bromide in the presence of a strong base, such as NaH in a solvent such as DMSO, in the range 0-85°C]. The resulting E/Z-mixture of a compound of formula (VI)

[where R3A is hydrogen or methyls may be converted to a compound of formula (VII) by the application of the Simmons Smith reaction (Zn/Cu, CHzIz, ether as solvent) to the olefin group of the compound of formula (VI). The reduction of the nitro group of the corresponding compound of formula (VII) may be performed using the conditions described in Scheme 1, to produce a compound of formula (IIA).

Scheme 3 A compound of formula (I) may be prepared by reacting a compound of formula Het-C (=O)-R* [where R* is halogen, hydroxy or Cl 6 alkoxy, but preferably chloro] with a compound of formula (II) as prepared above in the presence of a base (such as triethylamine, Hunig base, sodium bicarbonate, sodium carbonate, potassium carbonate, pyridine or quinoline, but preferably triethylamine) and in a solvent (such as diethylether, TBME, THF, dichloromethane, chloroform, DMF or NMP) for between 10minutes and 48hours (preferably 12 to 24hours) and between 0°C and reflux (preferably 20 to 25°C). When R* is hydroxy, a coupling agent [such as benzotriazol-1- yloxytris (dimethylamino) phosphoniumhexafluorophosphate, bis- (2-oxo-3- oxazolidinyl) -phosphinic acid chloride, N, N'-dicyclohexylcarbodiimide or 1,1'- carbonyl-diimidazole] may be used.

Scheme 4 A compound of formula (IA) (IA)

[where R3A is hydrogen or methyls may be prepared by the reduction of the nitro group of a compound of formula (VI) [where R3A is hydrogen or methyl] using standard conditions (for example, catalytic reduction or Bechamp-reduction) followed by amidation with an acid chloride to provide a compound of formula (VII) [where R3A is hydrogen or methyl] which is subsequently used in a Simmons-Smith reaction (Zn/Cu, CH2I2, ether as solvent) to provide a compound of formula (IA).

Surprisingly, it has now been found that the novel compounds of formula (I) have, for practical purposes, a very advantageous spectrum of activities for protecting plants against diseases that are caused by fungi as well as by bacteria and viruses.

The compounds of formula (I) can be used in the agricultural sector and related fields of use as active ingredients for controlling plant pests. The novel compounds are distinguished by excellent activity at low rates of application, by being well tolerated by plants and by being environmentally safe. They have very useful curative, preventive and systemic properties and are used for protecting numerous cultivated plants. The compounds of formula I can be used to inhibit or destroy the pests that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time protecting also those parts of the plants that grow later e. g. from phytopathogenic microorganisms.

It is also possible to use compounds of formula (I) as dressing agents for the treatment of plant propagation material, in particular of seeds (fruit, tubers, grains) and plant cuttings (e. g. rice), for the protection against fungal infections as well as against phytopathogenic fungi occurring in the soil.

Furthermore the compounds according to present invention may be used for controlling fungi in related areas, for example in the protection of technical materials, including wood and wood related technical products, in food storage, in hygiene management, etc.

The compounds of formula (I) are, for example, effective against the phytopathogenic fungi of the following classes: Fungi imperfecti (e. g. Botrytis, Pyricularia, Helminthosporium, Fusarium, Septoria, Cercospora and Alternaria) and Basidiomycetes (e. g. Rhizoctonia, Hemileia, Puccinia). Additionally, they are also effective against the Ascomycetes classes (e. g. Venturia and Erysiphe, Podosphaera, Monilinia, Uncinula) and of the Oomycetes classes (e. g. Phytophthora, Pythium, Plasmopara). Outstanding activity has been observed against powdery mildew (Erysiphe spp. ). Furthermore, the novel compounds of formula I are effective against phytopathogenic bacteria and viruses (e. g. against Xanthomonas spp, Pseudomonas spp, Erwinia amylovora as well as against the tobacco mosaic virus).

Within the scope of present invention, target crops to be protected typically comprise the following species of plants: cereal (wheat, barley, rye, oat, rice, maize, sorghum and related species); beet (sugar beet and fodder beet); pomes, drupes and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries) ; leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans, groundnuts); cucumber plants (pumpkins, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, paprika); lauraceae (avocado, cinnamomum, camphor) or plants such as tobacco, nuts, coffee, eggplants, sugar cane, tea, pepper, vines, hops, bananas and natural rubber plants, as well as ornamentals.

The compounds of formula (I) are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of formulation. To this end they are conveniently formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations e. g. in polymeric substances.

As with the type of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The compositions may also contain further adjuvants such as stabilizers, antifoams, viscosity regulators, binders or tackifiers as well as fertilizers, micronutrient donors or other formulations for obtaining special effects.

Suitable carriers and adjuvants can be solid or liquid and are substances useful in formulation technology, e. g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Such carriers are for example described in WO 97/33890.

The compounds of formula (I) are normally used in the form of compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession with further compounds. These further compounds can be e. g. fertilizers or micronutrient donors or other preparations which influence the growth of plants. They can also be selective herbicides as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application promoting adjuvants customarily employed in the art of formulation.

The compounds of formula (I) can be mixed with other fungicides, resulting in some cases in unexpected synergistic activities. Mixing components which are particularly preferred are azoles, such as azaconazole, BAY 14120, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, imiben- conazole, ipconazole, metconazole, myclobutanil, pefurazoate, penconazole, pyrifenox, prochloraz, propiconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triflumizole, triticonazole; pyrimidinyl carbinole, such as ancymidol, fenarimol, nuarimol; 2-amino-pyrimidines, such as bupirimate, dimethirimol, ethirimol; morpholines, such as dodemorph, fenpropidine, fenpropimorph, spiroxamine, tridemorph ; anilinopyrimidines, such as cyprodinil, mepanipyrim, pyrimethanil ; pyrroles, such as fenpiclonil, fludioxonil; phenylamides, such as benalaxyl, furalaxyl, metalaxyl, R-metalaxyl, ofurace, oxadixyl; benzimidazoles, such as benomyl, carbendazim, debacarb, fuberidazole, thiabendazole; dicarboximides, such as chlozolinate, dichlozoline, iprodione, myclozoline, procymidone, vinclozoline; carboxamides, such as carboxin, fenfuram, flutolanil, mepronil, oxycarboxin, thifluzamide; guanidines, such as guazatine, dodine, iminoctadine; strobilurines, such as azoxystrobin, kresoxim-methyl, metominostrobin, SSF-129, trifloxystrobin, picoxystrobin, BAS 500F (proposed name pyraclostrobin), BAS 520; dithiocarbamates, such as ferbam, mancozeb, maneb, metiram, propineb, thiram, zineb, ziram; N-

halomethylthiotetrahydrophthalimides, such as captafol, captan, dichlofluanid, fluoromides, folpet, tolyfluanid; Cu-compounds, such as Bordeaux mixture, copper hydroxide, copper oxychloride, copper sulfate, cuprous oxide, mancopper, oxine-copper; nitrophenol-derivatives, such as dinocap, nitrothal-isopropyl ; organo-p-derivatives, such as edifenphos, iprobenphos, isoprothiolane, phosdiphen, pyrazophos, tolclofos-methyl; various others, such as acibenzolar-S-methyl, anilazine, benthiavalicarb, blasticidin-S, chinomethionate, chloroneb, chlorothalonil, cyflufenamid, cymoxanil, dichlone, diclomezine, dicloran, diethofencarb, dimethomorph, SYP-LI90 (proposed name: flumorph), dithianon, ethaboxam, etridiazole, famoxadone, fenamidone, fenoxanil, fentin, ferimzone, fluazinam, flusulfamide, fenhexamid, fosetyl-aluminium, hymexazol, iprovalicarb, IKF-916 (cyazofamid), kasugamycin, methasulfocarb, metrafenone, nicobifen, pencycuron, phthalide, polyoxins, probenazole, propamocarb, pyroquilon, quinoxyfen, quintozene, sulfur, triazoxide, tricyclazole, triforine, validamycin, zoxamide (RH7281).

A preferred method of applying a compound of formula (1), or an agrochemical composition which contains at least one of said compounds, is foliar application. The frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen. However, the compounds of formula I can also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the compounds in solid form to the soil, e. g. in granular form (soil application). In crops of water rice such granulates can be applied to the flooded rice field. The compounds of formula I may also be applied to seeds (coating) by impregnating the seeds or tubers either with a liquid formulation of the fungicide or coating them with a solid formulation.

A formulation [that is, a composition containing the compound of formula (I)] and, if desired, a solid or liquid adjuvant, is prepared in a known manner, typically by intimately mixing and/or grinding the compound with extenders, for example solvents, solid carriers and, optionally, surface active compounds (surfactants).

The agrochemical formulations will usually contain from 0.1 to 99% by weight, preferably from 0.1 to 95% by weight, of the compound of formula I, 99.9 to 1% by weight, preferably 99.8 to 5% by weight, of a solid or liquid adjuvant, and from 0 to 25% by weight, preferably from 0.1 to 25% by weight, of a surfactant.

Advantageous rates of application are normally from 5g to 2kg of active ingredient (a. i. ) per hectare (ha), preferably from lOg to lkg a. i. /ha, most preferably from 20g to 600g a. i. /ha. When used as seed drenching agent, convenient dosages are from 10mg to Ig of active substance per kg of seeds.

Whereas it is preferred to formulate commercial products as concentrates, the end user will normally use dilute formulations.

The following non-limiting Examples illustrate the above-described invention in more detail.

EXAMPLE 1 This Example illustrates the preparation of Compound No. 1.5.

To a mixture of 17.4g (O. lmol) (2-isobutyl-cyclopropyl) benzene and 80ml of acetic acid anhydride was added a solution of 6. 0g (0. 095mol) nitric acid and 40ml acetic acid anhydride in such a manner that the internal temperature was kept constant at - 30°C. The resulting reaction mixture was stirred for lhour at-30°C and then for 2hours at 0°C. Then the mixture was poured onto 500ml of ice water and extracted three times with hexane. The hexane phases were combined and twice washed with 5% aqueous bicarbonate solution. After drying of the organic phase over sodium sulphate and distilling off the solvent in a water jet vacuum, the crude reaction product was obtained.

Purification by flash chromatography over silica get (eluant: ethylacetate/hexane 1: 10) yielded 10.5g of a yellow oil (mixture of para-and ortho-nitroisomers) which was directly used in the next step. This isomeric mixture [consisting of 10.5g (0. 048mol) 1- (2-isobutyl-cycloproply) 2-nitrobenzene and 1- (2-isobutyl-cyclopropyl)-4- nitrobenzene] was dissolved in 110ml of ethanol and hydrogenated over 5% Pt/C catalyst for 45minutes. After the theoretical uptake of hydrogen had occurred, the catalyst was filtered off and the solvent was removed in vacuo. The crude isomeric aniline mixture was purified by flash chromatography (eluant: ethylacetate/hexane 1: 2).

Yield: 6.38g of 2- (2-isobutyl-cyclopropyl) phenyl amine was obtained as a yellow oil (cis/trans mixture).

EXAMPLE 2 This Example illustrates the preparation of Compound 3.17.

A solution of 0. 35g (0. 0018mol) 1-methyl-4-trifluoromethyl-pyrrole-3-carboxylic acid and 0.24g (0. 0019mol) oxalylchloride in 15ml methylenechloride was stirred for

3hours at room temperature in the presence of two drops of absolute DMF. Then the acid chloride solution was slowly added to a solution of 0. 34g (0. 0018mol) 2- (2-isobutyl-cyclopropyl) phenylamine, 0.27g (0. 0027mol) triethylamine and 10ml methylene chloride. The resulting mixture was then stirred for 16hours at room temperature. After removal of the solvent in vacuo, the crude material was taken up in ca. 100ml ethylacetate. The ethylacetate phase was twice washed with water and after drying the organic phase, the solvent was again distilled off in a water jet vacuum. The crude product was purified by flash chromatography (eluant: hexane/ethylacetate/methylene chloride 1: 2: 2).

Yield: 0.52g 1-methyl-4-trifluoromethyl-lH-pyrrole-3-carboxylic acid [2- (2- isobutyl-cyclopropyl) phenyl] amide in the form of a white powder (cis/trans-mixture).

Step 1: In a sulfonation flask, NaH (12.8g ; 0. 32mol) was added to absolute DMSO (600ml). After heating at 80°C for 90minutes, cyclopropylcarbonylmethyltriphenyl phosphoniumbromide (136. 5g ; 0. 32mol) was added portionwise at room temperature.

The resultant suspension was stirred for 30minutes at room temperature and then a solution of 2-bromobenzaldehyde (59.4g ; 0. 32mol) in absolute DMSO (100mi) was added dropwise. After heating the resultant mixture for 4hours at 50°C, the mixture was poured onto 2. 51itres of ice water. Extraction with ethylacetate, drying over sodium sulfate and distilling off the solvent in a water jet vacuum yielded the crude product.

Purification was achieved by vacuum distillation.

Yield: 77.6g of E-3-(2-bromophenyl)-1-cyclopropylpropenone as a yellow oil (b. p.: 125-130°C at 0.3mbar).

Step 2: In a sulfonation flask, a mixture of of E-3-(2-bromophenyl)-1-cyclo- propylpropenone (77.6g ; 0. 309mol) and hydrazine hydrate (23.2g ; 0. 464mol) in ethanol (25ml) was heated at reflux temperature for 2hours. Then powdered potassium hydroxide (85%) (24.4g ; 0. 37mol) was added and the excesses of hydrazine hydrate and solvent were distilled out of the flask. The remaining mixture was then heated at a

temperature of 205-210°C for 3hours. The resultant resin was dissolved in ethylacetate (500ml) at a temperature of 50°C and the organic phase was washed twice with water.

Drying of the ethylacetate phase over sodium sulfate and distilling off the solvent in a water jet vacuum gave the raw material, which was purified by flash chromatography over silica gel (eluant: hexane/methylene chloride 7: 1).

Yield: 61.2g of 2- (2-bromophenyl) bicyclopropyl in the form of a slightly yellowish oil (cis/trans-mixture).

Step 3: A mixture of 2- (2-bromophenyl) bicyclopropyl (28. 5g ; 0. 12mol), benzophenoneimine (26. 1g ; 0. 144mol), sodium tertiary butoxide (16. 1g ; 0. 168 mol), tris-dibenzyl-ideneacetonedipalladium (Pd2dba3) (0.43g ; 0.474mmol), racemic 2,2'-bis (diphenylphosphino) 1, 1'-binaphthyl (BINAP) (0.83g ; 1.34mmol) and absolute toluene (450ml) was heated at reflux temperature under an atmosphere of nitrogen for 6hours. Then the solvent was removed in a water jet vacuum and the residue was taken up in ethylacetate (750ml). The organic layer was washed three times with brine and then dried over sodium sulfate. After evaporation of the solvent, the crude product was obtained. Purification was achieved by using flash chromatography over silica gel (eluant: hexane/methylene chloride 5: 1).

Yield: 39.9g of cis-/trans-mixture of benzhydrilidene (2-bi-cyclopropyl-2-yl- phenyl) amine in the form of a brownish oil.

Step 4: In a sulfonation flask, hydroxylamine hydrochloride (0.35g ; 0. 0048mol), sodium acetate (0.53g ; 0. 0064mol) and absolute methanol (30ml) were stirred at room temperature for about 15minutes. Then a solution of benzhydrilidene (2-bicyclopropyl- 2-yl-phenyl) amine (0.9g ; 0.00267 mol) in methanol (15ml) was added dropwise. The resultant mixture was stirred for lhour at room temperature. After dilution with ethylacetate (250ml), the organic phase was washed twice with water. After drying the organic phase (sodium sulfate) and distilling off the solvent in a water jet vacuum, the crude product was obtained. The final purification and separation of the cis-and trans-isomers was achieved by using flash chromatography (eluant: hexane/ethylacetate 5 : 1).

Yield: 0.21g of trans-and 0. 15g of cis-2-bicyclopropyl-2-yl-phenylamine in the form of brownish oils.
