The invention relates also to the production of these substances, as well as to microbicidal compositions which contain as active ingredient at least one of these compounds. The invention moreover relates to the use of these active ingredients, or of the stated compositions, for combating harmful microorganisms. <br><br> There are embraced herein compounds of the general formula I <br><br> OR-. N=- <br><br> 1 / <br><br> R.— CH — N <br><br> wherein R^ is 2,4-dichlorophenyl, 2-chloro-4-fluoro-phenyl, 2-fluoro-4-chlorophenyl, 2-chloro-4-bromophenyl, 4-chlorophenyl or 4-fluorophenyl; R£ is C^-Cg-cyclo-alkyl or C^-C^-alkyl; R^ is benzyl, chlorobenzyl, di-chlorobenzyl, C^-C^-alkyl or C^-C^-alkenyl; <br><br> and the acid addition salts, quaternary azolium salts and metal complexes thereof. By alkyl is meant, the following groups: methyl, ethyl, propyl, butyl, and isomers thereof, such as isopropyl, isobutyl, tert-butyl, and the like. Alkenyl is for example: propenyl-(1), <br><br> allyl, butenyl-(l), butenyl-(2) or butenyl-(3). Cycloalkyl is, for example: cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl. <br><br> The present invention hence relates to the free organic molecules of the formula I, and to addition salts, quaternary azolium salts and metal complexes. N^ <br><br> jty z <br><br> 22 JAN W86 <br><br> 202629 <br><br> -2- <br><br> The free molecules are preferred. <br><br> Examples of salt-forming acids are inorganic acids: hydrohalic acid, such as hydrofluoric acid, hydrochloric acid, hydrobromic acid or hydriodic acid, as well as sulfuric acid, phosphoric acid, phosphorous acid or nitric acid; and organic acids, such as acetic acid, trifluoro-acetic acid, trichloroacetic acid, propionic acid, glycolic acid, thiocyanic acid, lactic acid, succinic acid, citric acid, benzoic acid, cinnamic acid, oxalic acid, formic acid, benzenesulfonic acid, p-toluenesulfonic acid, methane-sulfonic acid, salicylic acid, p-aminosalicylic acid, 2-phenoxybenzoic acid or 2-acetoxybenzoic acid. <br><br> Metal complexes of the formula I consist of the basic organic molecule and an inorganic or organic metal salt, for example: the halides, nitrates, sulfates, phosphates, acetates, trifluoroacetates, trichloroacetates, propionates, tartrates, sulfonates, salicylates, benzoates, and so forth; of the elements of the third and fourth main groups,, such as aluminium, tin or lead, and also of the first to eighth subgroups, such as chromium, manganese, iron, zirconium, cobalt, nickel, copper, zinc, silver, mercury, and the like. The subgroup elements of the 4th period are preferred. The metals can be present here in the various valencies in which they occur. The metal complexes of the formula I can be mononuclear or polynuclear in form, that is to say, they can contain one or more organic molecule constituents as ligands. Complexes with the metals: copper, zinc, manganese, zirconium and tin are preferred. <br><br> The compounds of the formula I at room temperature are stable oils, resins or solids, which are distinguished by very valuable microbicidal properties. They can be used in agriculture or in related fields in a preventive and <br><br> 202629 <br><br> -3- <br><br> The active substances of the formula I according to the invention are characterised by very good microbicidal activity, and by their great ease of application. <br><br> Within the scope of the present invention, the following substituent types and combinations of these substituents with one another are preferred by virtue of their pronounced microbicidal action: <br><br> for R-^ : 2,4-dichlorophenyl, 2-chloro-4-bromophenyl, <br><br> 4-chlorophenyl, 4-fluorophenyl; <br><br> for R2 : methyl, iso-C^H^ or sec-C^Hg; <br><br> for : C^-C^-alkyl, allyl, proparyl, benzyl, 2,6- <br><br> Individual compounds preferred in particular are for example: <br><br> 1-(IH-1,2,4-triazol-l-yl)-2-benzyloxy-2-(2,4-dichlorophenyl)-pentane, <br><br> 1-(IH-1,2,4-triazol-l-yl)-2-methoxy-2-(2,4-chlorophenyl)-pentane, <br><br> 1-(IH-1,2,4-triazol-l-yl)-2-methoxy-2-(4-fluorophenyl)-2-cyclohexy1-ethane, <br><br> 1-(IH-1,2,4-triazol-l-yl)-2-n-propoxy-2-(2,4-dichlorophenyl)- <br><br> non +- an o phenyl)-pentane, and <br><br> 1-(IH-1,2,4-triazol-l-yl)-2-(p-chlorobenzyloxy)-2-(2 ,4-dichlorophenyl)-propane. <br><br> The compounds of the formula I can be produced according to the invention by reacting a compound of the formula II <br><br> dichlorobenzyl, 4-chlorobenzyl, or 2,4-dichlorobenzyl. <br><br> A <br><br> Ri * CH0R. <br><br> 1 i 2 4 <br><br> (II) <br><br> R, <br><br> '2 <br><br> 20Z629 <br><br> -4- <br><br> with a compound of the formula III <br><br> Vw <br><br> (III), <br><br> wherein the substituents R^, are as defined under the formula I, R^ is the IH-1,2,4-triazol-l-yl group, A and W are each -OH, -0M or one of the customary removable groups, M is an alkali metal atom or alkaline-earth metal atom, with the proviso that the choice of the reactants II and III is always such that either an MO or HO function reacts with a removable group or two hydroxyl functions react with each other. <br><br> A customary removable group is to be understood, here and in the following, as being substituents such as halogens [for example: fluorine, chlorine, bromine or iodine, preferably chlorine or bromine]; sulfonyloxy groups, preferably -0S02~R^; acyloxy groups, preferably -OCO-R,.; and isourea groups, preferably -0-C=NR^, wherein R.., R,. <br><br> , o Ob <br><br> NHR? <br><br> and Rj independently of one another are each C^-C^-alkyl or C-^-C^-haloalkyl, or phenyl which is unsubstituted or substituted by halogen, methyl, nitro, trifluoromethyl and/or methoxy. <br><br> In so far as alcohols or alcoholates of the formula II <br><br> are concerned (A = OH or OM), compounds of the formula I will in practice be produced by customary etherification with a compound of the formula III wherein W is a halide, preferably a chloride or bromide. The reaction is carried out in the temperature range of 0° to 150°C, either not in a solvent or, preferably, in atropic solvents, such as aromatic and aliphatic hydrocarbons, ethers and ethereal compounds (diethyl ether, dioxane, tetrahydrofuran [THF], and so forth), acetonitrile, dimethylformamide [DMF], and others familiar to the expert in the case of etherification reactions. To be recommended also is the productic in the phase-transfer process. <br><br> 22 JAM 1986 <br><br> -5- <br><br> 202625 <br><br> Alcohols of the formula II (A=0H) are for the most part known from the literature, or they can be produced by methods analogous to those described therein. <br><br> The compounds of the formula I contain, in the position adjacent to the oxygen function, an asymmetric centre (*) <br><br> 0R3 <br><br> Rj }* CH2R4 (I), <br><br> and can therefore be present in two enantiomeric forms. There is generally formed in the production of these substances a mixture of both enantiomeric forms; and this <br><br> can then, be separated, by the customary methods of enantiomer separation, for example by fractional crystallisation of a diastereoisomeric salt mixture with an optically active strong acid, or by column-chromatography 5 on an optically active carrier and with an optically active eluting agent, into the optical antipodes. The two antipodes exhibit a different microbicidal activity. Except where specially emphasised, there exists in all cases where reference is made to a compound of the formula I 10 a mixture of both enantiomeric forms. <br><br> It has been shown that the active substances of the formula I, and compositions containing them, exhibit, for practical purposes, a very favourable microbicidal spectrum, in particular against phytopathogenic fungi. The compounds 15 of the formula I thus have a very favourable curative, <br><br> preventive and systemic action for the protection of plants, especially cultivated plants, without affecting these in a disadvantageous manner. <br><br> The microorganisms occurring on plants or on parts of 20 plants (fruit, blossom, foliage, stalks, tubers or roots) of various cultivated crops can be inhibited or destroyed with the active substances of the formula I,, and also parts of plants subsequently growing remain preserved from such microorganisms. The active substances of the formula I 25 are effective against the phytopathogenic fungi belonging to the following classes: Fungi imperfecti (for example Botrytis, Helminthosporium, Fusarium, Septoria, Cercospora and Alternaria); Basidiomycetes (for example the species: Hemileia, Rhizoctonia and Puccinia); in particular they 30 are effective against the Ascomycetes class (for example: Venturia, Podosphaera, Erysiphe, Monilinia and Uncinula). Furthermore, the compounds of the formula I have a systemic action. They can be used also as dressing <br><br> 202 <br><br> agents for the treatment of seed (fruits, tubers and grain), and of plant cuttings to protect them from fungus infections, and also against phytopathogenic fungi occurring in the soilc <br><br> 5 The invention relates also to compositions which contain, as at least one active ingredient, a compound of the formula I, and also to the use of these compositions, or of the active ingredients on their own, for combating and/or preventing an infestation by microorganisms. <br><br> 10 Within the scope of this invention, target crops with respect to the range of indications disclosed herein include for example the following species of cultivated plants: cereals: (wheat, barley, rye, oats, rice, sorghum and related cereals); beet: (sugar beet and fodder beet); <br><br> 15 pomaceous fruit, stone fruit and soft fruit: (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries); legumes: (beans, lentils, peas and soya-bean); oil plants: (rape, mustard, poppy, olives, sunflowers, coco, castor-oil plants, cocoa and groundnuts); <br><br> 20 Cucurbitacea: (pumpkins, cucumbers and melons); fibre plants: (cotton, flax, hemp and jute); citrus fruits: (orangesj lemons, grapefruit and mandarins); varieties of vegetables: (spinach, lettuce, asparagus, varieties of cabbage, carrots, onions, tomatoes, potatoes and paprika); <br><br> 25 laurel plants: (avocado, cinnamon and camphor); or plants such as maize, tobacco, nuts, coffee, sugar beet, tea, grapevines, hops, bananas and natural rubber plants. <br><br> Plants within the scope of the present invention are however also all types of other green vegetation, whether it be <br><br> 30 in the form of ornamental plants (composites), areas of grass, embankments or general low cover crops. <br><br> Active substances of the formula I are customarily used in the form of compositions, and can be applied, simul- <br><br> 2026 2 <br><br> taneously or successively, with further active substances to the area or plants to be treated. These further active substances can be fertilisers, trace-element agents or other preparations influencing plant growth. They can 5 however also be selective herbicides, insecticides, <br><br> fungicides, bactericides, nematicides or molluscicides, or mixtures of several of these preparations, optionally together with carriers commonly used in formulation practice, tensides or other additives facilitating 10 application. <br><br> Suitable carriers and additives can be solid or liquid and they correspond to the substances customarily employed in formulation practice, for example: natural or regenerated mineral substances, solvents, dispersing agents, wetting 15 agents, adhesives, thickeners, binders or fertilisers. <br><br> The compounds of the formula I are used either in an unmodified form or preferably together with auxiliaries customarily employed in formulation practice, and are thus processed in a known manner for example into the form 20 of emulsion concentrates, brushable pastes, directly sprayable or dilutable solutions, diluted emulsions, <br><br> wettable powders, soluble powders, dusts or granulates, and also encapsulations in for example polymeric substances, The application processes, such as spraying, atomising, dusting, 25 scattering, brushing or pouring, and likewise the type of composition, are selected to suit the objectives to be achieved and the given conditions. Favourable applied amounts ar.e in general between 10 g and 5 kg of active substance (AS) per hectare, preferably between 100 g and 30 2 kg of AS per hectare, and in particular between 200 g and 600 g of AS per hectare. <br><br> The formulations, that is to say, the compositions <br><br> 2026 2 <br><br> -x? <br><br> or preparations containing the active substance of the formula I and optionally a solid or liquid additive, are produced in a known manner, for example by the intimate mixing and/or grinding of the active substances with extenders, such as with solvents, solid carriers and optionally surface-active compounds (tensides). These measures are familiar to one skilled in the art. <br><br> Suitable solvents are: aromatic hydrocarbons, preferably the fractions Cg to such as xylene mixtures or substituted naphthalenes, phthalic esters, such as dibutyl-or dioctylphthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols, as well as ethers and esters thereof, such as ethanol, ethylene glycol, ethylene glycol monomethyl or -ethyl ether, ketones, such as cyclohexanone, strongly polar solvents, such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethyl formamide, and also optionally epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water. <br><br> The solid carriers used, for example for dusts and dispersible powders, are as a rule natural mineral fillers, such as calcite, talcum, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to use highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example: pumice, ground brick, sepiolite or bentonite; and suitable nonsorbent carriers are for example calcite or sand. In addition, a great number of pre-granulated materials of inorganic or organic nature can be used, such as in particular dolomite or ground plant residues. <br><br> Suitable surface-active compounds are, depending on the nature of the active substance of the formula I to be formulated, nonionic, cationic and/or anionic tensides <br><br> 202629 <br><br> - 10 - <br><br> having good emulsifying, dispersing and wetting properties. By 'tensides' are also meant mixtures of tensides. <br><br> The tensides customarily used in formulation practice are described, inter alia, in the following publications: <br><br> 5 "Mc Cutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ringwood, New Jersey, 1980, and Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc. New York, 1980. <br><br> The agrochem'ical preparations contain as a rule 0.1 to 10 99%, particularly 0.1 to 9570, of active, substance of the formula I, 99.9 to 1%, especially 99.8 to 5%, of a solid or liquid additive, and 0 to 25%, in particular 0.1 to 25%, of a tenside. Whereas commercial products are preferably in the form of concentrated compositions, the 15 compositions employed by the end-user are as a rule diluted. <br><br> The following Examples serve to further illustrate the invention without limiting the scope thereof. Temperature values are given in degrees Centigrade, and percentages 20 and 'parts' relate to weight, RT = room temperature and absolute = anhydrous, Example I is included to illustrate the process of production. <br><br> 2026 2 <br><br> - &gt;5 - <br><br> Production Examples Example 1: Production of <br><br> NaH/CH3J <br><br> II <br><br> V ii ii <br><br> ^ / ii <br><br> 1-(IH-1,2,4-Triazol-l-yl)-2-phenyl-2-(2,4-dichlorophenyl)-5 2-methoxy-ethane <br><br> 1.8 g (0.041 mol) of sodium hydride dispersion (about 55% strength) in mineral oil are suspended, in a nitrogen atmosphere, twice with petroleum ether; and 50 ml of DMF are subsequently added.

The mixture is stirred at RT for a further 16 hours; it is subsequently poured into ice-water, and extracted twice with ethyl acetate. The combined extracts are washed four times with semi-saturated sodium chloride solution, dried over sodium sulfate, 20 filtered, and concentrated by evaporation. The residue is suspended at reflux temperature with diethyl ether; it is finally cooled to RT and filtered; yield: 10.9 g of colourless crystals, m.p. 128-131°C. <br><br> I§ <br><br> 202^2 <br><br> Example 2: Production of <br><br> NaH/BrCH0CcHr Z O D <br><br> (KJ) <br><br> 1-(IH-1,2,4-Triazol-l-yl)-2-benzyloxy-2-(2,4-dichloro phenyl) -pentane <br><br> 5 To a suspension of 2.4 g of 55% sodium hydride in 100 ml of absolute DMF (adhering mineral oil is washed away beforehand with hexane) is added dropwise, in a nitrogen atmosphere, a solution of 15 g of 1-(1H-1,2,4-triazol-l-yl)-2-(2,4-dichlorophenyl)-pentan-2-ol in 40 ml 10 of absolute DMF and 10 ml of absolute THF. After the exothermic reaction has subsided, stirring is maintained for 1 hour at 50°C, and 1 g of potassium iodide is subsequently added. There are then added dropwise 9.6 g of benzyl bromide in 10 ml of DMF; the reaction mixture is stirred at 15 RT for 12. hours, and is afterwards poured into ice-water. The cloudy emulsion is saturated with sodium chloride, and repeatedly extracted with ethyl acetate. The combined extracts are washed with semi-saturated sodium chloride solution, dried over sodium sulfate, filtered, and concen-20 trated by evaporation.
