Abstract

O.Z. 0050/40923 ABSTRACT OF THE DISCLOSURE: 3-Anilinobenzoisothiazoles of the formula

Description

20~a~ 6 O.Z. 0050/~0923 3-Anilinobenzoisothiazoles and funqicides con~aining these The present invention relates to novel, valuable 3-anilinobenzoisothiazoles, a process for the preparation S thereof, fungicidal agents containing these compounds, and the use thereof as fungicides.
It has been disclosed (EP 244 705) that 2-anil-inobenzothiazoles, eg. 2-(2,6-dinitro-3-chloro-4-tri-fluoromethylanilino)-6-methoxybenzothiazole or 2-(2,6-dinitro-3-chloro-4-trifluoromethylanilino)-6-nitrobenzo-thiazole, have a good fungicidal action. HoweYer, the action is not always satisfactory at low application rates and use concentrations.
We have now found, surprisingly, that 3-anilino-benzoisothiazoles of the formula I

m~ H02 Rl N~R 2 where X is hydrogen, NO2, CN, halogen, SO2-C1-C4-alkyl, Cl-C4-alkyl,C3-C6-cycloalkyl,Cl-C4-haloalkyl,Cl-C4-alkoxy, Cl-C4-haloalkoxy, Cl-C4-alkylthio, or phenoxy or phenylthio each of which is unsubstituted or substi-tuted in the phenyl, m is an integer from 1 to 4, with the individual radicals being identical or different when m is greater than 1, Rl is hydrogen, halogen, Cl-C4-alkoxy, Cl-C4-haloalkyl, Cl-C4-alkylthio, C1-C4-haloalkoxy, or phenoxy, phenyl-thio, benzyloxy or benzylthio each o f which is unsubstituted or substituted in the phenyl, R2 and R3 are, independently of one anoth~r, hydrogen, NO2, halogen, CN, C1-Cs-alkyl, SO2-C1-C4-alkyl, C1-C6-haloalkyl, So2NR3R6, Cl-C4-haloalkoxy, CoOR5 or CoNR5R6, 202041~

- 2 - O.Z. OOS0/40923 R~ is hydrogen, CooR7, CoNR5R6, CHO, CQR7 or So~R7, R5 and R6 are, independently of one another, hydrogen or Cl-C4-alkyl, R7 is Cl-C~-alkyl, C~-C4-haloalkyl, benzyl, or aryl which is substituted or unsubstituted, and the salts thereof which are tolerated by plants have a very good fungicidal action while being excellently tolerated by plants.
The term alkyl, as such or as part of another substituent, such as haloalkyl, alkoxy, alkylthio and haloalkoxy, means, depending on the number of stated carbon atoms, the following straight-chain or branched groups: in particular C1-C4-alkyl, methyl, ethyl, n-propyl, iso-propyl, n-butyl, sec-butyl, iso-butyl, tert-butyl, n-pentyl and n-hexyl. The prefix halo in the name of a substituent means, here and hereinafter, that this substituent can contain one or more halogen atoms. Halo represents F, Cl, Br or I. Thus haloalkyl is a mono- to perhalogenated alkyl such as CH2Cl, CHCl2, CCl3, CH2F, CHF2, CF3, CH2Br, CHBrCl, CF2Cl, C2Cl$, C2F5, CHF2, CF2-CHF2, CH2CH2Cl, CH2CH2Br, C3F7 or C4Fg.
Cycloalkyl is cyclopropyl, cyclobutyl, cyclo-pentyl and cyclohexyl, it being possible for the rings to be substituted by one or two methyls, such as 1-methyl-cyclopropyl, 2-methylcyclopropyl, 2,2-dimethylcyclo-propyl, l-methylcyclopentyl or 1-me~hylcyclohexyl.
Examples of aryl which is substituted or unsub-stituted are phenyl, Cl-C4-alkylphenyl, 2-, 3- and 4-tolyl, halophenyl~ 4-bromophenyl, 4-chlorophenyl, 4-I-~fluorophenyl~ nitrophenyl, 2-nitrophenyl, 4-nitrophenyl, and 1- and 2-naphthyl.
Where phenoxy, phenylthio, benzyloxy or benzyl-thio is substituted the aromatic ring carries one to ~hree halogens, such as 2-Cl, 2-F, 3-Cl, 4-Cl, 4-Br, 2,3-Cl2, 2,4-Cl2, 2,5-Cl2, 2,6-C12, 3,5-C12, 2,4,6-C13or 3,4,5-Cl3, or one or two substituents such as nitro or methyl, 2-NO2, 4~NO2, 2-CH3, 4-CH3, 2,6-(CH3)2 or 3,5-(CH3)2.

202~

- 3 - O.Z. 0050/40923 Examples of suitable cations for the salts are Na~, Li , K+, Mg2+, Fe3~, NH4~, singly or multiply al~ylated, hydroxyalkylated and/or arylated ammonium cations such as diisopropylammonium, tetramethylammonium, tetrabutyl-ammonium, trimethylbenzyla~monium, N,N-dimethylanilinium or trimethyl(2-hydroxyethyl)ammonium, where the alkyl has l to 4 carbon atoms and the aryl is phenyl or benzyl.
The compounds of the formula I as claimed in claim 1, in which R4 is hydrogen, are prepared, for example, by reacting a benzoisothiazole of the formula II
~S~
m ~ II

where X and m have the meanings specified in claim 1, with compounds of the formula III

Rl NO2 ~ R2 III
Y ~

where Rl, R2 and R3 ha~e the meanings specified in claim 1, with or without a solvent or diluent, in the presence or absence of an organic or inorganic base, at from -20 to 200C, where Y and Z are different from one another and are NHz or halogen.
In both cases, the reaction takes place with elimination of hydrogen halide. This is why it is advan-~tageous to use acid-binding agents or bases in both cases.
Bases and acid-binding agents which can be used are organic or inorganic compounds such as alkali metal and alkaline earth metal hydroxides (LiOH, NaOH, ROH, Ca(OH) 2 ) ~ oxides (Na2O, Li2O, CaO, MgO), hydrides (LiH, NaH, KH, CaH2), amides (LiNH2, NaNH2, RNH2), carbonates (Li2CO3, Na2CO3, CaC03), bicarbonates (NaHCO3), alkyls 2020~6 - 4 - O.z. 0050/40923 ~butylLi, CH3Li, cH3Mgcl)r C t -C5-alc oholates (NaOCH3, NaOC~H5~ KOC7H5, KO-tert-butyl, ~g(OCH3).), amines, especi-ally tertiary amines (eg. trimethylamine, triethylamine, diisopropylethylamine, N-methylpiperidine), pyridine, substituted pyridines (collidine, lutidines, 4-dLmethyl-aminopyridine), and bicyclic amines.
The reactions can be carried out in the presence of inert solvents or diluents.
Suitable examples are aliphatic and aromatic hydrocarbons such as toluene, xylenes, cyclohexane, petroleum ether; halohydrocarbons such as chlorobenzene, methylene chloride, chloroform; ethers such as dialkyl ethers (diethyl ether, diisopropyl ether, tert-butyl methyl ether etc.), anisole, dioxane, tetrahydrofuran;
nitriles such as acetonitrile, propionitrile; N,N-di-alkylated amides such as dimethylformamide; dimethyl sulfoxide; ketones such as acetone, diethyl ketone, tert-butyl methyl ketone, methyl ethyl ketone; alcohols such as methanol, ethanol, n- and iso-propanol, butanols, especially tert-butanol, and mixtures of such solvents.
The reaction temperature can be varied within wide limits. It is advantageously from -20C to 200C or the boiling point of the solvent or solvent mixture, depending on the nature of the substituents X, R1, RZ, R3, R5, R5 and R7 and the nu~ber m thereof.
It may also be advantageous in some cases to carry out the reac~ion under a protective gas and/or in anhydrous solvents. Suitable pro~ective gases are inert gases such as helium, argon and, preferably, nitrogen.
~-~ The starting compounds are known or can be easily prepared by known methods. The haloaromatic compounds (or the phenols which can easily be converted into these) and anilines which are used are known.
The following citations relate to 3-amino- and 3-halo-benzoisothiazoles: DE-A 3112164, DE 1915387, DE

The compounds of the formula I as claimed in 202n4l6 - 5 - O.Z. 0050/40923 claim 1, with the proviso that R4 is different from hydrogen, are prepared, for example, by reacting a 3-anilinobenzoisothiazole of the formula I in which R4 is hydrogen, and X, m, R1, R2, R3, Rs, R and R7 have the S meanings specified in claLm 1, with an acylating or sulfonating agent of the formula IV

where R4 has the meaning specified in claim 1, apart from hydrogen, and L is a nucleophilically displaceable leaving group, in the presence or absence of a solvent or diluent and in the presence or absence of an organic or inorganic base at from -20C to 150C.
Suitable and preferred nucleophilically displace-able groups are halogens such as F, Cl, Br and I, sulfo-nates (methanesulfonate, benzenesulfonate etc.), alcohol-ates (ethylate, benzylate etc.) and carboxylates (acetate etc.).
~ he bases which can be used are the same com-pounds as for the preparation of compounds of the formula I (R4 = H) from compounds of the formulae II and III.
The reactions are generally carried out at from - 20C to 150C or at the boiling point of the solvent or solvent mixture.
One or more inert solvents or diluents can be present in the reaction. Suitable examples are aliphatic and aromatic hydrocarbons such as toluene, xylenes, cyclohexane, petroleum ether; halohydrocarbons such as '~chlorobenzene, methylene chloride, ethylene chloride, chloroform, tetrachloroethylene; ethers such as dialkyl ethers (diethyl ether, diisGpropyl ether, tert-butyl methyl ether etc.~, anisole, dioxane, tetrahydrofuran;
nitriles such as acetonitrile, propionitrile; N,N-dialky-lated amides such as dimethylformamide; dimethyl sulf-oxide; ketones such as acetone, diethyl ketone, methyl ethyl ketone, tert-butyl methyl ketone, and mixtures of 202~-~16 - 6 - O.Z. 0050/40923 such solvents.
The novel compounds are isolated by conventional methods. The resulting products can be purified by recrystalli~ation, extraction or chromatography. The 5following examples are intended to illustrate the prepar-ation:

A solution of 23.5 g (0.21 mol) of potassium tert-butylate in 250 ml of tert-butanol is added drop-10wise, at 0C to 5C, in the course of 1 hour to a vigor-ously stirred suspension of 19.5 g (0.1 mol) of 3-amino-5-nitrobenzoisothiazole and 32 g (0.105 mol) of 2,4-dichloro-3,5-dinitrobenzotrifluoride in 300 ml of 1:1 tet.rahydrofuran/tert-butanol. After a further hour at 150C, the mixture is warmed to room temperature and acidified with glacial acetic acid, 500 ml of water are added, and the precipitate is filtered off with suction and washed with cold methanol; 36.1 g (78 %) of compound 1.46, yellow crystals, melting point 168-170C.

0.24 g (0.01 mol) of sodium hydride is added a little at a time to a solution of 3.4 g (0.01 mol) of 3-(2-nitro-4-trifluoromethylanilino~benzoisothiazole (compound 1.20) in 25 ml of tetrahydrofuran. After 2515 minutes, 2.0 g (0.02 mol) of acetic anhydride are added dropwise at room temperature. After 48 h at 20C, 150 ml of water are added, and the mixture is extracted 3 times with 100 ml of ether each tLme. The combined ether extracts are washed with saturated brine, dried " over MgSO~ and concentrated. The residue is chromato-graphed (silica gel, 19:1 cyclohexane/ethyl acetate).
1.3 g (34 %) of compound 2.4 are obtained as pale yellow crystals, melting point 108 to 111C, in addition to 1.4 g of starting material.

6.5 ml of a 40 % strength aqueous solution of tetrabutylammonium hydroxide (0.01 mol) are added 2 0 2 ~ 6 - 7 - O.Z. 0050/40923 dropwise to a still hot solution of 4.6 g (0.01 mol) of compound 1.46 (5-nitro-3-(2,6-dinitro-3-chloro-4-tri-fluoromethylanilino)benzoisothiazole) in 150 ml of ethanol.. After cooling, the precipitate is filtered off with suction and washed with ethanol and diisopropyl ether; 5.4 g (75 %) of compound 3.7, dark red crystals, melting point 143C.

Generally speaking, the novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the Asco-mycetes and Basidiomycetes classes. So~e of them have a systemic action and can be used as foliar and soil fun~icides.
The fungicidal compounds are of particular interest for controlling a large number of fungi in various crops or their seeds, especially wheat, rye, barley, oats, rice, Indian corn, lawns, cotton, soybeans, coffee, sugar cane, fruit and ornamentals in horticulture and viticulture, and in vegetables such as cucumbers, beans and cucurbits.
The noYel compounds are particularly useful for controlling the following plant diseases:

~0~41~

22 O.Z. OOS0/40923 Erysiphe graminis in cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits, Podosphaera leucotricha in apples, Uncinula necator in vines, 5 Puccinia species in cereals, Rhizoctonia species in cotton and lawns, Ustilago species in cereals and sugar cane, Venturia inaequalis (scab) in apples, Helminthosporium species in cereals, 10 Septoria nodorum in wheat, Botrytis cinerea (gray mold) in strawberries and grapes, Cercospora arachidicola in groundnuts, Pseudocercosporella herpotrichoides in wheat and barley, Pyricularia oryzae in rice, 15 Phytophthora infestans in potatoes and tomatoes, Fusarium and Verticillium species in various plants, Plasmopara viticola in grapes, Alternaria species in vegetables and fruit.
20 The compounds are applied by spraying or dusting the plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They may be applied before or after infection of the plants or seeds by the fungi. Either the fungi themselves, or the objects to be protected against fungal attack are treated with a fungicidally effective 25 amount of the active ingredient.
The novel substances can be converted into conYentional formulations such as solutions, emulsions, suspensions, dusts, powders, pastes and granules.
The application forms depend entirely on the purposes for which they are 3Q intended; they should at all events ensure a fine and uniform distribution of the active ingredient. The formulations are produced in known manner, for example by extending the active ingredient with solvents and/or carriers, with or without the use of emulsifiers and dispersants; if water is used as solvent, it is also possible to employ other organic solvents 35 as auxiliary solvents. Suitable auxiliaries for this purpose are solvents such as aromatics (e.g., xylene~, chlorinated aromatics (e.g., chlorobenz-enes), paraffins (e.g., crude oil fractions), alcohols te.g., methanol, butanol), ketones (e.g., cyclohexanone), amines (e.g., ethanolamine, dimethylformamide), and water; carriers such as ground natural minerals 40 (e.g., kaolins, aluminas, talc and chalk) and ground synthetic minerals ~e.g., highly disperse silica and silicates); emulsifiers such as nonionic and anionic emulsifiers (e.g., polyoxyethylene fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dispersants such as lignin, sulfite waste liquors and methylcellulose.

202~16 23 O.Z. 0050/40923 The fungicidal agents generally contain from 0.1 to 95, and preferably from 0.5 to 90, wt% of active ingredient. The application rates are from 0.02 to 3 kg or more of active ingredient per hectare, depending on the type of effect desired. The novel compounds may also be used for protect-5 ing materials (wood), for example against Paecilomyces variotii.
When the active ingredients are used for treating seed, amounts of from0.001 to 50, and preferably from 0.01 to 10, 9 per kg of seed are usually employed.
The agents and the ready-to-use formulations prepared from them, such as solutions, emulsions, suspensions, powders, dusts, pastes and granules, are applied in conventional manner, for example by spraying, atomizing, dusting, scattering, dressing or watering.
Examples of formulations are given below.

2(~2~416 O.Z. 0050/40923 Use Example 1 Action on Botrytis cinerea in pimientos 5 Pimiento seedlings of the "Neusiedler Ideal Elite" variety with 4 to 5 well developed leaves were sprayed to runoff with aqueous suspensions containing (dry basis) 80% of active ingredient and 20% of emulsifier.
After the sprayed-on layer had dried, the plants were sprayed with a conidial suspension of the fungus 8Otrytis cinerea and kept in a high-10 humidity chamber at 22 to 24C. After 5 days, the disease had spread onthe untreated control plants to such an extent that the necroses covered the major portion of the leaves. The leaf attack was assessed.
The results show that active ingredient 1.46, applied as a 0.05wt% spray, 15 has a better fungicidal action ~97%) than prior art active ingredients A
(3~%) and B (2~%).
Use Example 2 20 Action on Plasmopara viticola Leaves of potted vines of the MUller~Thurgau variety were sprayed with aqueous liquors containing (dry basis) 80% of active ingredient and 20% of emulsifier. To assess the duration of action, ths plants were set up, 25 after the sprayed-on layer had dried, for 8 days in the gr~enhouse. Then the leaves were infected with a zoospore suspension of Plasmopara viti-cola. rhe plants were first placed for 48 hours in a water vapor-saturated chamber at 24C and then in a greenhouse for 5 days at from 20 to 30C. To accelerate and intensify the sporangiophore discharge, the plants were 30 then again placed in the moist chamber for 16 hours. The extent of fungus attack was then assessed on the undersides of the leaves.
The results show that active ingredients 1.1, 1.16, 1.33, 1.46 and 1.82, applied as 0.05wt# spray liquors, have a better fungicidal action l100#) 35 than prior art comparative agents A (65%) and B (65%).
Use Example 3 Action on Phytophthora infestans Leaves of potted tomatoes of the "Gro~e Fleischtomate" variety were sprayed with aqueous liquors consisting (dry basis) of 8~% of active ingredient and 20% of ~mulsifier. After 24 hours, the leaves were inf~cted with a zoospore suspension of the fungus Phytophthora infestans. The ~0.~416 26 O.z. 0050/40923 plants were set up in a water vapor-saturated chamber at 16 to 18C. After 6 days the disease had spread to such an extent on the untreated but infected control plants that the fungicidal action of the compounds was able to be assessed.

The results show that active ingredients 1.16, 1.33, 1.46 and 1.82, applied as 0.025wt% spray liquors, have a better fungicidal action (97%) than prior art comparative agents A (20%) and B (50%~.
