Description

The present invention relates to the use of substituted tert.-butanol derivatives, which have not yet been described, as fungicidal agents.
It has already been disclosed that certain diazolyl derivatives, such as, for example, 2-(4-chlorophenyl)- or -(2-chlorophenyl)-1,3-di(1,2,4-triazol-1-yl)-2-propanol and 2-(4-chlorophenyl)-1,3-di(imidazol-1-yl)-2-propanol, have good fungicidal properties (compare EP-OS (European Published Specification) No. 0,044,605). However, the action of these compounds is not always completely satisfactory, especially when low amounts and concentrations are applied.
It has been found that the substituted tert.-butanol derivatives of the general formula ##STR2## in which R.sup.1, R.sup.2 and R.sup.3 are identical or different and represent azolyl, optionally substituted phenoxy, optionally substituted phenylthio, alkylthio, alkenyl, alkinyl, optionally substituted phenylacetylenyl, alkylamino, dialkylamino, optionally substituted phenylamino, optionally substituted phenyl-N-alkyl-amino, optionally substituted cycloalkylamino, optionally substituted cycloalkyl-N-alkyl-amino, aminoethoxy, alkylaminoethoxy or dialkylaminoethoxy,
and acid addition salts and metal salt complexes thereof have good fungicidal properties.
Surprisingly, the substituted tert.-butanol derivatives of the formula (I) to be used according to the invention have a better fungicidal activity than the diazolyl-deriatives 2-(4-chlorophenyl)- or -(2-chlorophenyl)-1,3-di(1,2,4-triazol-1-yl)-2-propanol and 2-(4-chlorophenyl)-1,3-di(imidazol-1-yl)-2-propanol, which are already known from the prior art and are closely related compounds structurally and from the point of view of their action.

R.sup.1 --H (II)
in which
R.sup.1 has the abovementioned meaning, (a) with 2,2-dihalogenomethyloxiranes of the formula ##STR48## in which Hal represents halogen, in the presence of an inert organic solvent, such as, for example, acetone, and in the presence of an acid-binding agent, such as, for example, potassium carbonate, at temperatures between 20.degree. and 120.degree. C., or

C.
The nucleophiles of the formula (II) are generally known compounds of organic chemistry.
2,2-dihalogenomethyloxiranes of the formula (III) are known (compare Beilstein, E III (1), pages 1587-1588), and can be obtained in a known manner, in which 3-halogeno-2-halogenomethylpropenes of the formula ##STR51## in which Hal has the abovementioned meaning, either are first reacted with tert.-butyloxy halide to give 1,3-dihalogeno-2-halogenomethyl-2-propanols of the formula ##STR52## in which Hal has the abovementioned meaning, and these are then epoxidized in the presence of calcium hydroxide to give the desired 2,2-dihalogenomethyloxiranes of the formula (III) (in this context, compare also Beilstein, E III (1), pages 1587-1588); or are epoxidized directly in the presence of peracids, such as, for example, peracetic acid or m-chloroperbenzoic acid, to give the desired 2,2-dihalogenomethyloxiranes of the formula (III).
The 2-halogenomethyloxiranes of the formula (IV) are not yet known. However, they can be obtained in the generally customary manner, by either reacting 2,2-dihalogenomethyloxiranes of the formula (III) with a nucleophile of the formula (II); or first reacting 3-halogeno-2-halogenomethyl-propenes of the formula (VI) with a nucleophile of the formula (II), if necessary in the form of an alkyli metal salt, to give propenes of the formula ##STR53## in which Hal and R.sup.1 have the abovementioned meaning, and then epoxidizing these compounds in the presence of peracids to give the desired 2-halogenomethyloxiranes of the formula (IV).
The substituted oxiranes of the formula (V) are not yet known. However, they can be obtained in the generally customary manner by either reacting 2,2-dihalogenomethyloxiranes of the formula (III) with a nucleophile of the formula (II); or reacting 3-halogen-2-halogenomethyl-propanes of the formula (VI) with a nucleophile of the formula (LI), if necessary in the form of an alkali metal salt, to give the propenes of the formula ##STR54## in which R.sup.1 has the abovementioned meaning, and then epoxidizing these compounds in the presence of peracids to give the desired oxiranes of the formula (V); or epoxidizing ketones of the formula ##STR55## in which R.sup.1 and R.sup.2 have the abovementioned meaning, with dimethylsulphonium methylide in a manner which is known per se.

R.sup.1 represents optionally substituted phenylthio, alkylthio, alkylamino, dialkylamino, optionally substituted phenylamino, optionally substituted phenyl-N-alkylamino, optionally substituted cycloalkylamino or optionally substituted cycloalkyl-N-alkyl-amino,
under the conditions of process (a).
The active compounds according to the invention exhibit a powerful microbicidal action and can be employed in practice for combating undesired microorganisms. The active compounds are suitable for use as plant protection agents.
Fungicidal agents in plant protection are employed for combating Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes.
The good toleration, by plants, of the active compounds, at the concentrations required for combating plant diseases, permits treatment of above-ground parts of plants, of vegetative propagation stock and seeds, and of the soil.
As plant protection agents, the active compounds according to the invention can be used with particularly good success for combating cereal diseases, such as Erysiphe graminis, Leptosphaeria nodorum, Puccinia sp., Cochliobolus sativus and Pyrenophora teres; Sphaerotheca species, such as Sphaerotheca fuliginea, and rice diseases, such as Pyricularia and Pellicularia. Moreover, the active compounds according to the invention display a broad in vitro fungicidal action spectrum.
When applied in appropriate amounts, the compounds according to the invention also exhibit a plant growth-regulating action.
The active compounds can be converted to the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, foams, pastes, soluble powders, granules, aerosols, suspension-emulsion concentrates, seed treatment powders, natural and synthetic materials impregnated with active compound, very fine capsules in polymeric substances and in coating compositions for seed, and formulations used with burning equipment, such as fumigating cartridges, fumigating cans, fumigating coils and the like, as well as ULV cold mist and warm mist formulations.
These formulations are produced in known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surface-active agents, that is, emulsifying agents and/or dispersing agents, and/or foam-forming agents. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkyl naphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strong polar solvents, such as dimethylformamide and dimethylsulphoxide, as well as water; by liquefied gaseous extenders or carriers are meant liquids which are gaseous at normal temperature and under normal pressure, for example aerosol propellants, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide; as solid carriers there are suitable: for example ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly-dispersed silicic acid, alumina and silicates; as solid carriers for granules there are-suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and grnaules of organic material such as sawdust, coconut shells, corn cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulphonates, alkyl sulphates, aryl sulphonates as well as albumin hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, can be used in the formulations.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations in general contain between 0.1 and 95 percent by weight of active compound, preferably between 0.5 and 90%.
The active compounds according to the invention can be present in the formulations or in the various use forms as a mixture with other known active compounds, such as fungicides, bactericides, insecticides, acaricides, nematicides, herbicides, bird repellents, growth factors, plant nutrients and agents for improving soil structure.
The active compounds can be used as such or in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, emulsions, suspensions, powders, pastes and granules. They are used in the customary manner, for example by watering, immersion, spraying, atomizing, misting, vaporizing, injecting, forming a slurry, brushing on, dusting, scattering, dry dressing, moist dressing, wet dressing, slurry dressing or encrusting.
In the treatment of parts of plants, the active compound concentrations in the use forms can be varied within a substantial range. They are, in general, between 1 and 0.0001% by weight, preferably between 0.5 and 0.001%.
In the treatment of seed, amounts of active compound of 0.001 to 50 g per kilogram of seed, preferably 0.01 to 10 g, are generally required.
For the treatment of soil, active compound concentrations of 0.00001 to 0.1% by weight, preferably 0.0001 to 0.02% by weight, are required at the place of action.
