Sulphonyltriazol derivatives and their use for combating micro-organisms

It is already known that certain benzotriazole derivatives have fungicidal properties (cf. DE-A 195 23 446). Thus, for example, 1-(3,5-dimethyl-isoxazole4-sulphonyl)-1H-benzotriazole can be used for controlling fungi. The activity of this substance is good; however, it is sometimes unsatisfactory at low application rates.

This invention, accordingly, provides novel sulphonyltriazole derivatives of the formula

in which

Hal represents fluorine, chlorine or bromine,

R

1

represents hydrogen, alkyl, alkoxyalkyl, cycloalkyl, alkylaminocarbonyl, optionally substituted phenyl, optionally substituted phenoxy or represents optionally substituted heterocyclyl and

R

2

represents alkyl or represents optionally substituted heterocyclyl or represents a radical of the formula

in which

R

3

represents halogen, alkyl or phenyl,

R

4

represents hydrogen or alkyl and

R

5

represents alkyl or optionally substituted phenyl, or

R

4

and R

5

together with the nitrogen atom to which they are attached form a heterocyclic ring which may be substituted and may also contain an additional heteroatom.

Furthermore, it has been found that sulphonyltriazole derivatives of the formula (I) are obtained when triazoles of the formula

in which

R

1

and Hal are as defined above,

are reacted with sulphonyl halides of the formula

R

2

—SO

2

—Hal

1

(III)

in which

R

2

is as defined above and

Hal

1

represents chlorine or bromine,

if appropriate in the presence of an acid binder and if appropriate in the presence of a diluent.

Finally, it has been found that the sulphonyltriazole derivatives of the formula (I) have very good microbicidal properties and can be used for controlling undesirable microorganisms in crop protection and in agriculture.

Surprisingly, the sulphonyltriazole derivatives of the formula (I) according to the invention have considerably better fungicidal activity than 1-(3,5-dimethyl-isoxazole-4-sulphonyl)-1H-benzotriazole, which is a known active compound of the same direction of action and of similar constitution.

The sulphonyltriazole derivatives according to the invention are in each case defined substances; however, their structure cannot always be defined unambiguously. They can be present as compounds of one of the formulae

or else as isomer mixtures.

The notation chosen for the formula (I) is meant to indicate that the positions of the double bonds in the triazole ring and the point of attachment of the —SO

2

—R

2

group cannot always be determined unambiguously.

The formula (I) provides a general definition of the substances according to the invention.

The process according to the invention is generally carried out under atmospheric pressure. However, it is also possible to operate under elevated or reduced pressure—in general between 0.1 bar and 10 bar.

For carrying out the process according to the invention, in general from 1 to 2 mol, preferably from 1 to 1.3 mol, of sulphonyl halide of the formula (III) and, if appropriate, from 1.0 to 2.0 mol, preferably from 1.0 to 1.3 mol, of acid acceptor are employed per mole of triazole of the formula (II).

Work-up is carried out by customary methods. In general, the reaction mixture is poured into water, the resulting mixture is extracted repeatedly with an organic solvent that is sparingly soluble in water and the combined organic phases are dried and concentrated under reduced pressure. The residue that remains can, if desired, be freed by customary purification methods of any impurities that are still present.

The compounds according to the invention have a potent microbicidal action and can be employed for controlling undesirable microorganisms, such as fungi and bacteria, in crop protection and in the protection of materials.

The fact that the active compounds are well tolerated by plants at the concentrations required for controlling plant diseases permits the treatment of aerial parts of plants, of propagation stock and seeds, and of the soil.

The active compounds according to the invention can be employed particularly successfully for controlling diseases in viticulture and fruit and vegetable growing, such as, for example, against Phytophthora species.

The active compounds according to the invention are also suitable for increasing the yield of crops. Moreover, they have reduced toxicity and are tolerated well by plants.

In the protection of materials, the compounds according to the invention can be employed for protecting industrial materials against infestation with, and destruction by, undesired microorganisms.

Industrial materials in the present context are understood as meaning non-living materials which have been prepared for use in industry. For example, industrial materials which are intended to be protected by active compounds according to the invention from microbial change or destruction can be adhesives, sizes, paper and board, textiles, leather, wood, paints and plastic articles, cooling lubricants and other materials which can be infested with, or destroyed by, microorganisms. Parts of production plants, for example cooling-water circuits, which may be adversely affected by proliferation of microorganisms may also be mentioned within the scope of the materials to be protected. Industrial materials which may be mentioned within the scope of the present invention are preferably adhesives, sizes, paper and boards, leather, wood, paints, cooling lubricants and heat-transfer liquids, particularly preferably wood.

Microorganisms capable of degrading or changing the industrial materials which may be mentioned are, for example, bacteria, fungi, yeasts, algae and slime organisms.

Depending on their particular physical and/or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and microencapsulations in polymeric substances and in coating compositions for seeds, and ULV cool and warm fogging formulations.

These formulations are produced in a 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 surfactants, that is emulsifiers and/or dispersants, and/or foam formers. If the extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide or dimethyl sulphoxide, or else water. Liquefied gaseous extenders or carriers are to be understood as meaning those liquids which are gaseous at standard temperature and under atmospheric pressure, for example aerosol propellants such as halogenated hydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly disperse silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks. Suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkylsulphates, arylsulphonates, or else protein hydrolysates. Suitable dispersants are: for example lignin-sulphite waste liquors and methylcellulose.

Tackifiers 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, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colourants 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 generally comprise between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be used as such or in their formulations also mixed with known fungicides, bactericides, acaricides, nematicides or insecticides in order thus, for example, to widen the spectrum of action or to prevent development of resistance. In many cases, synergistic effects are achieved, i.e. the activity of the mixture exceeds the activity of the individual components.

Examples of co-components in mixtures are the following compounds:

Fungicides:

It is also possible to admix other known active compounds, such as herbicides, or fertilizers and growth regulators.

The active compounds can be used as such or in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. They are used in the customary manner, for example by pouring, spraying, atomizing, spreading, dusting, foaming, brushing on and the like. It is further possible to apply the active compounds by the ultra-low volume method or to inject the active compound formulation, or the active compound itself, into the soil. The seed of the plants can also be treated.

When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the type of application. In the treatment of parts of plants, the application rates of active compounds are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1000 g/ha. In the treatment of seed, the application rates of active compounds are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. In the treatment of the soil, the application rates of active compound are generally between 0.1 and 10000 g/ha, preferably between 1 and 5000 g/ha.

The compositions used for protecting industrial materials comprise the active compounds generally in an amount of from 1 to 95% by weight, preferably from 10 to 75% by weight.

The use concentrations of the active compounds according to the invention depend on the species and the occurrence of the microorganisms to be controlled, and on the composition of the material to be protected. The optimum rate of application can be determined by test series. The use concentrations are generally in the range from 0.001 to 5% by weight, preferably from 0.05 to 1.0% by weight, based on the material to be protected.

The activity and the activity spectrum of the active compounds to be used according to the invention in the protection of materials, or the compositions, concentrates or quite generally formulations preparable therefrom, can be increased by adding, if appropriate, other antimicrobially active compounds, fungicides, bactericides, herbicides, insecticides or other active compounds for broadening the activity spectrum or obtaining particular effects, such as, for example, the additional protection against insects. These mixtures may have a broader activity spectrum than the compounds according to the invention.

The preparation and use of active compounds according to the invention are illustrated by the following examples.

The sulphonyl-triazole derivatives of the formula (I) according to the invention can also be used for treating transgenic plants. In combination with the substances formed by expression, it is possible for synergistic effects to occur.

PREPARATION EXAMPLES

Example 1

At room temperature, a solution of 1.8 g (10 mmol) of 3-phenyl-5-chloro-1,2,4-triazole in 40 ml of acetonitrile is mixed with stirring with 1.4 g (10 mmol) of potassium carbonate and then stirred at room temperature for 10 minutes. 2.0 g (10 mmol) of 3,5-dimethyl-isoxazole4-sulphonyl chloride are then added, and the mixture is stirred at room temperature for another 20 hours. For work-up, the reaction mixture is poured into 150 ml of water. The resulting mixture is extracted twice with in each case 40 ml of methylene chloride. The combined organic phases are dried over sodium sulphate and concentrated under reduced pressure. The residue that remains is chromatographed on silica gel using the mobile phase methylene chloride. This gives 1.7 g (50% of theory) of 3-phenyl-5-chloro-2-(3,4-dimethyl-isoxazole-4-sulphonyl)-1,2,4-triazole in the form of a solid of melting point 70 to 74° C. log p: 3.67

The sulphonyltriazole derivatives of the formula (I) listed in the table below are also prepared by the method given above.
