[0015] Furthermore, the invention relates to processes for the preparation of these compounds, to compositions comprising them, and to their use for controlling harmful fungi.

[0016] WO-A 97/08135, DE-A 197 10 609 and WO-A 99/27783 disclose acylaminosalicylamides for controlling harmful fungi.

[0017] However, their action is unsatisfactory in many cases.

[0018] It is an object of the invention to provide compounds with an improved action.

[0019] We have found that this object is achieved by the compounds defined at the outset. Moreover, there have been found processes for their preparation, compositions comprising them and methods of controlling phytopathogenic harmful fungi using the compounds I.

[0020] The compounds of the formula I differ from those of the prior art by the hydrazide group.

[0021] The compounds of the formula I show an increased efficacy against harmful fungi compared with the known compounds.

[0022] Compounds of the formula I can be prepared for example starting from alkyl salicylates of the formula II where A is C1-C4-alkoxy and Z is a protecting group which can be eliminated under acidic conditions, such as, for example, an acetyl group.

[0023] Compounds of the formula II can be obtained by free-radical halogenation under generally customary conditions, especially advantageously by bromination with N-bromosuccinimide (NBS) using azobisisobutyronitrile (AIBN) as free-radical initiator with exposure to light [cf. J. Amer. Chem. Soc., Vol. 71 (1949), p. 2137 et seq; ibid., Vol. 90 (1968), p. 1797 et seq]. Compounds of the formula II where A is methoxy, Z is acetyl and Hal is bromine are preferred.

[0024] This reaction is usually carried out at temperatures of from 20° C. to 150° C., preferably from 50° C. to 100° C., in an inert organic solvent [cf. Can. J. Chem., Vol. 33 (1955), p. 1819; J. Org. Chem., Vol. 49 (1984), p. 2158].

[0025] Suitable solvents are halogenated hydrocarbons such as carbon tetrachloride, chloroform and chlorobenzene. Mixtures of the solvents mentioned may also be used.

[0026] In general, the starting materials are reacted with each other in equimolar amounts. It may be advantageous for the yield to employ NBS in an excess based on II.

[0027] The starting materials II required for the preparation of the compounds I are commercially available, known from the literature [Bull. Soc. Chim. Fr., Vol. 9 (1966), p. 2821; Biotechnol. Lett., Vol. 15 (1993), p. 469; J. Fluorine Chem., Vol. 74 (1995), p. 69] or can be prepared in accordance with the literature cited.

[0028] The dihalo compounds of the formula III are oxidized with elimination of the protecting group Z under acidic conditions to give the keto compounds IV.

[0029] This reaction is usually carried out at temperatures of from 20° C. to 150° C., preferably from 20° C. to 100° C., in an inert organic solvent in the presence of an acid (cf. Org. Synth., Vol. 20 (1940), p. 92].

[0030] Suitable solvents are aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, ethers, alcohols such as methanol, ethanol, n-propanol, isopropanol, n-butanol and tert-butanol, and also dimethyl sulfoxide, N,N-dimethylformamide and N,N-dimethylacetamide, especially preferably methanol, ethanol and n-propanol. Mixtures of the solvents mentioned may also be used.

[0031] Acids and acidic catalysts which are used are inorganic acids such as hydrofluoric acid, aqueous hydrochloric acid, hydrobromic acid, sulfuric acid and perchloric acid, Lewis acids such as boron trifluoride, aluminum trichloride, iron(III) chloride, tin(IV) chloride, titanium(IV) chloride and zinc(II) chloride, and organic acids such as formic acid, acetic acid, propionic acid, oxalic acid, toluenesulfonic acid, benzenesulfonic acid, camphorsulfonic acid, citric acid and trifluoroacetic acid.

[0032] In general, the acids are employed in catalytic amounts, but they may also be used in equimolar amounts, in an excess or, if appropriate, as solvents.

[0033] To prepare compounds I where A is NH2, NHCH3 or N(CH3)2, salicylic esters IV are reacted with ammonia or methylamine to give salicylamides of the formula IV.1 where R3 is hydrogen or methyl; the reaction with dimethylamine gives compounds of the formula IV.3:

[0034] This reaction is usually carried out at temperatures of from 20° C. to 150° C., preferably from 20° C. to 100° C., in an inert organic solvent [cf. Arch. Pharm. (1982), p. 941].

[0035] Suitable solvents are aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, ethers such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran, nitriles such as acetonitrile, alcohols, and dimethyl sulfoxide, N,N-dimethylformamide and N,N-dimethylacetamide, especially preferably N,N-dimethylformamide and N,N-dimethylacetamide. Mixtures of the solvents mentioned may also be used.

[0036] In general, the starting materials are reacted with each other in equimolar amounts. It may be advantageous for the yield to employ the amine in an excess based on IV.

[0037] The imino group is usually eliminated from IV.1 at temperatures of from 20° C. to 150° C., preferably from 20° C. to 100° C., in an inert organic solvent in the presence of an acid [cf. J. Chem. Soc. (1957), p. 3807; J. Org. Chem., Vol. 6 (1941), p. 489].

[0038] Suitable solvents are aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, ethers, alcohols such as methanol, ethanol, n-propanol, isopropanol, n-butanol and tert-butanol, and dimethyl sulfoxide, N,N-dimethylformamide and N,N-dimethylacetamide, especially preferably methanol, ethanol and n-propanol. Mixtures of the solvents mentioned may also be used.

[0039] Acids and acidic catalysts which are used are inorganic acids such as hydrofluoric acid, aqueous hydrochloric acid, hydrobromic acid, sulfuric acid and perchloric acid, Lewis acids such as boron trifluoride, aluminum trichloride, iron(III) chloride, tin(IV) chloride, titanium(IV) chloride and zinc(II) chloride, and organic acids such as formic acid, acetic acid, propionic acid, oxalic acid, toluenesulfonic acid, benzenesulfonic acid, camphorsulfonic acid, citric acid and trifluoroacetic acid.

[0040] To prepare compounds of the formula I where A is hydroxyl, the alkyl esters of the formula IV are hydrolyzed by customary methods to give the salicylic acids of the formula IV.4 [cf. Organikum [Organic chemistry], 16th Ed., pp. 415 and 622, VEB Deutscher Verlag der Wissenschaften, Berlin 1985]. This reaction is usually carried out at temperatures of from 10° C. to 80° C., preferably 20° C. to 60° C., in an inert organic solvent in the presence of a base, such as alkali metal hydroxides or alkaline earth metal hydroxides, in particular sodium hydroxide or potassium hydroxide.

[0041] Depending on the form which radical A in formula I takes, compounds of the formulae IV, IV.2, IV.3 or IV.4 are reacted with hydrazides of the formula V to give compounds of the formula I.

[0042] This reaction is usually carried out at temperatures of from 20° C. to 150° C., preferably from 20° C. to 80° C., in an inert organic solvent in the presence of an acid [cf. Org. Prep. Proced. Int., Vol. 30 (1998), p. 177; CH-A 661 276].

[0043] Suitable solvents are aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, ethers, nitrites, alcohols such as methanol, ethanol, n-propanol, isopropanol, n-butanol and tert-butanol, and dimethyl sulfoxide, N,N-dimethylformamide and N,N-dimethylacetamide, especially preferably methanol, ethanol, n-propanol, isopropanol or N,N-dimethylformamide. Mixtures of the solvents mentioned may also be used.

[0044] Acids and acidic catalysts which are used are inorganic acids such as hydrofluoric acid, aqueous hydrochloric acid, hydrobromic acid, sulfuric acid and perchloric acid, Lewis acids such as boron trifluoride, aluminum trichloride, iron(III) chloride, tin(IV) chloride, titanium(IV) chloride and zinc(II) chloride, and organic acids such as formic acid, acetic acid, propionic acid, oxalic acid, toluenesulfonic acid, benzenesulfonic acid, camphorsulfonic acid, citric acid and trifluoroacetic acid.

[0045] In general, the acids are employed in catalytic amounts, but they may also be used in equimolar amounts, in an excess or, if appropriate, as solvents.

[0046] In general, the starting materials are reacted with each other in equimolar amounts. It may be advantageous for the yield to employ V in an excess based on IV.

[0047] The reaction mixtures are worked up in the customary manner, for example by mixing with water, phase separation and, if appropriate, chromatographic purification of the crude products. Some of the intermediates and end products are obtained in the form of colorless or pale brown, viscous oils which are purified or freed from volatile components under reduced pressure and at a moderately elevated temperature. If the intermediates and end products are obtained as solids, they may also be purified by recrystallization or digestion.

[0048] If individual compounds I cannot be obtained by the above-described routes, they can be prepared by derivatizing the compounds I.

[0049] Upon their preparation, the compounds I may be obtained, owing to their C═C and C═N double bonds, as E/Z isomer mixtures which can be separated in the customary manner, for example by crystallization or chromatography, to give the individual compounds.

[0050] If, upon synthesis, isomer mixtures are obtained, separation is, however, not absolutely necessary since some of the individual isomers may be converted into each other during preparation for use, or upon use (for example with exposure to light, acids or bases). Similar conversions may also take place after use, for example in the treatment of plants in the treated plant or in the harmful fungus to be controlled.

[0476] The compounds I are suitable as fungicides. They are distinguished by an outstanding activity against a broad spectrum of phytopathogenic fungi, in particular from the classes of the Ascomycetes, Deuteromycetes, Phycomycetes and Basidiomycetes. Some of them act systemically, and they can be employed in crop protection as foliar- and soil-acting fungicides.

[0477] They are especially important for controlling a large number of fungi on a variety of crop plants such as wheat, rye, barley, oats, rice, maize, grass, bananas, cotton, soybean, coffee, sugar cane, grapevine, fruit species, ornamentals and vegetables such as cucumbers, beans, tomatoes, potatoes and cucurbits, and on the seeds of these plants.

[0498] Venturia species (scab) on apples and pears.

[0499] Moreover, the compounds I are suitable for controlling harmful fungi such as Paecilomyces variotii in the protection of materials (e.g. wood, paper, paint dispersions, fibers and fabrics) and in the protection of stored products.

[0500] The compounds I are applied by treating the fungi, or the plants, seed, materials or the soil to be protected against fungal infection, with a fungicidally active amount of the active ingredients. Application can be effected both before and after infection of the materials, plants or seeds by the fungi.

[0501] In general, the fungicidal compositions comprise from 0.1 to 95, preferably 0.5 to 90, % by weight of active ingredient.

[0502] When used in crop protection, the application rates are from 0.01 to 2.0 kg of active ingredient per ha, depending on the nature of the desired effect.

[0503] In the treatment of seeds, amounts of active ingredient of from 0.001 to 0.1 g, preferably 0.01 to 0.05 g, are generally required per kilogram of seed.

[0504] When used in the protection of materials or stored products, the application rate of active ingredient depends on the nature of the field of application and on the desired effect. Application rates conventionally used in the protection of materials are, for example, from 0.001 g to 2 kg, preferably from 0.005 g to 1 kg, of active ingredient per cubic meter of material treated.

[0505] The compounds I can be converted into the customary formulations, e.g. solutions, emulsions, suspensions, dusts, powders, pastes and granules. The use form depends on the particular purpose; it is intended to ensure in each case a fine and uniform distribution of the compound according to the invention.

[0506] The formulations are prepared in a known manner, e.g. by extending the active ingredient with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents as cosolvents if water is used as the diluent. Auxiliaries which are suitable are essentially: solvents such as aromatics (e.g. xylene), chlorinated aromatics (e.g. chlorobenzenes), paraffins (e.g. mineral oil fractions), alcohols (e.g. methanol, butanol), ketones (e.g. cyclohexanones), amines (e.g. ethanolamine, N,N-dimethylformamide) and water; carriers such as ground natural minerals (e.g. kaolins, clays, talc, chalk) and ground synthetic minerals (e.g. highly disperse silica, silicates); emulsifiers such as nonionic and anionic emulsifiers (e.g. polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants such as lignin-sulfite waste liquors and methylcellulose.

[0507] Suitable surfactants are alkali metal, alkaline earth metal and ammonium salts of lignosulfonic acid, naphthalenesulfonic acid, phenolsulfonic acid, dibutylnaphthalenesulfonic acid, alkylarylsulfonates, alkyl sulfates, alkylsulfonates, fatty alcohol sulfates and fatty acids and their alkali metal and alkaline earth metal salts, salts of sulfated fatty alcohol glycol ether, condensates of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensates of naphthalene or of naphthalenesulfonic acid with phenol or formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctylphenol, octylphenol, nonylphenol, alkylphenol polyglycol ethers, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignin-sulfite waste liquors and methylcellulose.

[0508] Substances which are suitable for the preparation of directly sprayable solutions, emulsions, pastes or oil dispersions are mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, e.g. benzene, toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes or their derivatives, methanol, ethanol, propanol, butanol, chloroform, carbon tetrachloride, cyclohexanol, cyclohexanone, chlorobenzene, isophorone, strongly polar solvents, e.g. N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone and water.

[0509] Powders, materials for spreading and dusts can be prepared by mixing or concomitantly grinding the active substances with a solid carrier.

[0510] Granules, e.g. coated granules, impregnated granules, homogeneous granules, can be prepared by binding the active ingredients on solid carriers. Examples of solid carriers are mineral earths such as silicas, silica gels, talc, kaolin, attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders and other solid carriers.

[0511] In general, the formulations comprise between 0.01 and 95% by weight, preferably between 0.1 and 90% by weight, of the active ingredient. The active ingredients are employed in a purity of from 90% to 100%, preferably from 95% to 100% (according to NMR spectrum).

[0512] The following are examples of formulations:

[0513] I. 5 parts by weight of a compound according to the invention are mixed intimately with 95 parts by weight of finely divided kaolin. This gives a dust which comprises 5% by weight of the active ingredient.

[0514] II. 30 parts by weight of a compound according to the invention are mixed intimately with a mixture of 92 parts by weight of pulverulent silica gel and 8 parts by weight of paraffin oil which had been sprayed onto the surface of this silica gel.

[0521] The active ingredients can be used as such, in the form of their formulations or the use forms prepared therefrom, e.g. in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; it is intended to ensure in each case the finest possible distribution of the active ingredients according to the invention.

[0522] 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.

[0523] The active ingredient concentrations in the ready-to-use products can be varied within relatively wide ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%.

[0524] The active ingredients may also be used successfully in the ultra-low-volume method (ULV), it being possible to apply formulations comprising over 95% by weight of active ingredient, or even to apply the active ingredient without additives.

[0525] Various types of oils, herbicides, fungicides, other pesticides, or bactericides may be added to the active ingredients, if appropriate immediately prior to use (tank mix). These agents can be admixed with the agents according to the invention in a weight ratio of 1:10 to 10:1.

[0526] In the use form as fungicides, the compositions according to the invention can also be present together with other active ingredients, e.g. with herbicides, insecticides, growth regulators, fungicides or else with fertilizers. Mixing the compounds I or the compositions comprising them in the use form as fungicides with other fungicides frequently results in a broader fungicidal spectrum of action.
