and to the plant-compatible acid addition salts or metal salts thereof.


Furthermore, the invention relates to the use of the compounds of the formula I for controlling phytopathogenic fungi and to compositions comprising these compounds.


Azolylmethyloxiranes, their preparation and their use in crop protection are known, for example, from EP-A 0 094 564 and EP-A 0 196 038.


Azolylmethyloxiranes which carry a hetaryl substituent on the oxirane ring are known from EP-A 0 421 125.


The azolylmethyloxiranes described already have good to very good fungicidal activity against a number of pathogens; however, it was the object of the present invention to provide novel azolylmethyloxiranes having improved fungicidal activity.


This object was achieved with the compounds of the formula I described at the outset.


Owing to the basic character of their nitrogen atoms, the compound I is capable of forming salts or adducts with inorganic or organic acids or with metal ions.


Examples of inorganic acids are hydrohalic acids, such as hydrogen fluoride, hydrogen chloride, hydrogen bromide and hydrogen iodide, carbonic acid, sulfuric acid, phosphoric acid and nitric acid.


Suitable organic acids are, for example, formic acid and alkanoic acids, such as acetic acid, trifluoroacetic acid, trichloroacetic acid and propionic acid, and also glycolic acid, thiocyanic acid, lactic acid, succinic acid, citric acid, benzoic acid, cinnamic acid, oxalic acid, alkylsulfonic acids (sulfonic acids having straight-chain or branched alkyl radicals of 1 to 20 carbon atoms), arylsulfonic acids or aryldisulfonic acids (aromatic radicals, such as phenyl and naphthyl, which carry one or two sulfonic acid groups), alkylphosphonic acids (phosphonic acids having straight-chain or branched alkyl radicals of 1 to 20 carbon atoms), arylphosphonic acids or aryldiphosphonic acids (aromatic radicals, such as phenyl and naphthyl, which carry one or two phosphoric acid radicals), where the alkyl or aryl radicals may carry further substituents, for example p-toluenesulfonic acid, salicylic acid, p-aminosalicylic acid, 2-phenoxybenzoic acid, 2-acetoxybenzoic acid, etc.


Suitable metal ions are in particular the ions of the elements of the second main group, in particular calcium and magnesium, of the third and fourth main group, in particular aluminum, tin and lead and also of transition groups one to eight, in particular chromium, manganese, iron, cobalt, nickel, copper, zinc, and others.

The use forms depend entirely on the intended purposes; the intention is to ensure in each case the finest possible distribution of the active compounds according to the invention.


Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.


The active compound concentrations in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1%.


The active compounds may also be used successfully in the ultra-low-volume process (ULV), by which it is possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.


Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active compounds, if appropriate not until immediately prior to use (tank mix). These compositions can be admixed with the compositions according to the invention in a weight ratio of from 1:100 to 100:1, preferably from 1:10 to 10:1.


The following are particularly suitable as adjuvants in this context: organically modified polysiloxanes, for example Break Thru S 240®; alcohol alkoxylates, for example Atplus 245®, Atplus MBA 1303®, Plurafac LF 300® and Lutensol ON 30®; EO-PO block polymers, for example Pluronic RPE 2035® and Genapol B®; alcohol ethoxylates, for example Lutensol XP 80®; and sodium dioctylsulfosuccinate, for example Leophen RA®.


The compositions according to the invention in the application form as fungicides can also be present together with other active compounds, for example with herbicides, insecticides, growth regulators, fungicides or else with fertilizers. When mixing the compounds I or the compositions comprising them with one or more further active compounds, in particular fungicides, it is in many cases possible, for example, to widen the activity spectrum or to prevent the development of resistance. In many cases, synergistic effects are obtained.


The present invention furthermore provides a combination of at least one azolylmethyloxirane of the formula I, in particular an azolylmethyloxirane disclosed in the present description as being preferred, and/or an agriculturally acceptable salt thereof and at least one further fungicidal, insecticidal, herbicidal and/or growth-regulating active compound, it being possible for a synergistic effect to occur.


The present invention also provides a pesticidal composition which comprises at least one compound of the formula I, in particular a compound of the formula I described in the present description as being preferred, and/or an agriculturally acceptable acid addition salt or metal salt thereof and at least one solid or liquid carrier. Such a pesticidal composition may comprise at least one further fungicidally, insecticidally and/or herbicidally active compound, it also being possible for a synergistic effect to occur.

SYNTHESIS EXAMPLES
1) Synthesis of 1-chloro-2-(4-chloro-2-fluorophenyl)-3-(2-chlorophenyl)propan-2-ol

Magnesium turnings (430 mg, 17.9 mmol) and iodine were added to a solution of 2-chlorobenzyl chloride (200 μl, 1.7 mmol) in anhydrous diethyl ether (20 ml). The reaction mixture was warmed slowly until the iodine color disappeared and the start of the reaction was indicated by the refluxing solvent. The remaining 2-chlorobenzyl chloride (2.0 ml, 15.3 mmol) was added dropwise such that the reaction mixture was kept at reflux. After the addition had ended, the mixture was stirred at room temperature for another 2 h and then cooled to 0° C. At this temperature, 4-chloro-2-fluorophenacetyl chloride (3.00 g, 14.5 mmol) in anhydrous toluene (10 ml) was added dropwise. The mixture was then warmed to room temperature and stirred for another 3 h. After this time, the mixture was again cooled to 0° C., and a saturated aqueous ammonium chloride solution (10 ml) was added. The organic phase was removed and the aqueous phase was extracted with ethyl acetate (2×20 ml). The combined organic extracts were dried over sodium sulfate and freed from the solvent. The crude product obtained in this manner (5.0 g) was used without purification for the next reaction step.


2) Synthesis of (Z)-4-chloro-1-[3-chloro-1-(2-chlorophenyl)prop-1-en-2-yl]1-2-fluorobenzene

At 0° C., first acetic anhydride (1.8 ml, 19.1 mmol) and then concentrated sulfuric acid (100 μl, 1.96 mmol) were added to a solution of 1-chloro-2-(4-chloro-2-fluorophenyl)-3-(2-chlorophenyl)propan-2-ol (5.0 g, approximately 14.5 mmol) in a 1,4-dioxane/THF mixture (44 ml, 10:1). The reaction mixture was then warmed to room temperature, stirred for another 18 h and subsequently cooled again to 0° C. At this temperature, saturated sodium chloride solution (20 ml) was added, and the mixture was neutralized using aqueous sodium hydroxide solution (6.2 ml, 50% w/w). The resulting mixture was extracted with ethyl acetate (3×20 ml), the organic phases were combined and dried over sodium sulfate. After filtration and removal of the solvent under reduced pressure, the residue was purified by column chromatography (silica gel, hexane). The appropriate fractions were combined, giving (Z)-4-chloro-1-[3-chloro-1-(2-chloro-phenyl)prop-1-en-2-yl]-2-fluorobenzene in the form of a colorless oil (1.40 g, 31% over 2 steps).



1H NMR (300 MHz, CDCl3) δ 8.01 (d, J=6.9 Hz, 1H), 7.46-7.37 (m, 4H), 7.22-7.10 (m, 2H), 6.8 (s, 1H), 4.50 (s, 2H).


3) Preparation of anti-2-(4-chloro-2-fluorophenyl)-2-(chloromethyl)-3-(2-chlorophenyl)-oxirane

Maleic anhydride (2.48 g, 25.3 mmol) and aqueous hydrogen peroxide solution (1.46 ml of a 50% strength solution, 25.3 mmol) were added to a solution of (Z)-4-chloro-1-[3-chloro-1-(2-chlorophenyl)prop-1-en-2-yl]-2-fluorobenzene (800 mg, 2.53 mmol) in acetic acid (20 ml). The reaction mixture was stirred at 45° C. for 3 d and then cooled to room temperature, and water (20 ml) and aqueous thiosulfate solution (10% solution, 4 ml) were added. The aqueous phase was extracted with dichloromethane (3×15 ml), and the combined organic phases were washed with sodium chloride solution (2×10 ml). The organic phase was dried over sodium sulfate and filtered off, and the solvent was distilled off. The residue obtained in this manner was purified by column chromatography (silica gel, 25:1 hexane/ethyl acetate). The appropriate fractions were combined, giving anti-2-(4-chloro-2-fluorophenyl)-2-(chloromethyl)-3-(2-chlorophenyl)oxirane (580 mg, 70%) in the form of a colorless solid.



1H NMR (300 MHz, CDCl3) δ 7.50 (t, J=9.0 Hz, 1H), 7.49-7.41 (m, 2H), 7.36-7.32 (m, 2H), 7.24-7.14 (m, 2H), 4.30 (s, 1H), 3.87 (d, J=12.0 Hz, 1H), 3.37 (d, J=12.0 Hz, 1 H).


4) Preparation of 1-[(anti-2-(4-chloro-2-fluorophenyl)-3-(2-chlorophenyl)oxiran-2-yl)-methyl]-1H-1,2,4-triazole

At room temperature, 1,2,4-triazole (362 mg, 5.24 mmol) and sodium hydride (130 mg, 5.42 mmol) were added to a solution of anti-2-(4-chloro-2-fluorophenyl)-2-(chloro-methyl)-3-(2-chlorophenyl)oxirane (580 mg, 1.74 mmol) in anhydrous N,N-dimethyl-formamide (20 ml). The mixture was stirred initially for 20 h at 60° C. and then for a further 4 h at 75° C. The mixture was then cooled to room temperature, diluted with ethyl acetate (20 ml) and washed with sodium chloride solution (3×15 ml). The organic phase was removed, dried over sodium sulfate and filtered, and the solvent was distilled off. The residue obtained in this manner was purified by column chromatography (silica gel, 7:3 hexane/ethyl acetate). The appropriate fractions were combined, giving the target compound (383 mg, 60%) in the form of a colorless solid.



1H NMR (300 MHz, CDCl3) δ 7.86 (s, 1H), 7.78 (s, 1H), 7.61-7.58 (m, 1H), 7.57-7.37 (m, 3H), 7.23-7.06 (m, 3H), 4.76 (d, J=12.0 Hz, 1H), 4.28 (s, 1H), 4.02 (d, J=12.0 Hz, 1H).
