Description

The present invention relates to novel acetylene derivatives and a method for controlling pests, in particular fungi, insects, nematodes and spider mites, with these compounds.

The compounds of the general formula I ##STR3## where U, V and W are each hydrogen,
A is ethylidene, methoxymethylidene or methoximino,
B is methoxy or methylamine and
R has the abovementioned meanings, are preferred.
Owing to the C.dbd.C or C.dbd.N double bonds, the novel compounds of the general formula I maybe obtained in the preparation as E/Z isomer mixtures. These can be separated into the individual components in a conventional manner, for example by crystallization or chromatography. Both the individual isomeric compounds and mixtures thereof form subjects of the invention and can be used as pesticides.
The compounds of the general formula I as claimed in claim 1 are prepared, for example, as described in the following schemes:
The novel compounds of the general formula I can be prepared by reacting, for example, an o-bromo compound 2 with a terminal acetylene derivative 3 in the presence of a transition metal catalyst, preferably a palladium compound, eg. Pd(PPh.sub.3).sub.4, PdCl.sub.2 or Pd(OAc).sub.2, in the presence of triphenylphosphine and in the presence of a base, for example an N-alkylamine, such as triethylamine, and in the presence or absence of a solvent or diluent, eg. dimethylformamide or acetonitrile (cf. for example L. Brandsma et al., Synth. Comm. 20(1990), 1889 and W. B. Austin et al., J. Org. Chem. 46(1981), 2280). ##STR4##
A, B, R, U, V and W have the meanings stated in claim 1.
Alternatively, the compounds of the general formula 1 are obtained by reacting the o-bromo-.alpha.-keto acid derivatives 4 with the acetylenes of the formula 3 (conditions similar to Scheme 1) ##STR5## and then reacting the resulting .alpha.-ketocarboxylic acid derivatives 5 a) for example in a wittig or a Wittig-Horner-Emmons reaction with a phosphonium ylide 6 or with a phosphonic acid derivative 7 (Scheme 3) to give the novel compounds of the formula 1, where B, U, V, W and R have the meanings stated in claim 1 and A is CH-alkyl, CH-alkoxy or CH-thioalkyl (cf. for example C. Ferri, Reaktionen der organischen Synthese, Thieme Verlag, Stuttgart, page 354 et seq., 1978), or
R'=CH.sub.3, M.sup..sym. =alkali metal ion
Scheme 3
b) with an O-alkylhydroxylamine 8, in the presence or absence of an acid, eg. hydrochloric acid, or of a ##STR6## bse, eg. K.sub.2 CO.sub.3, to give the novel compounds of the formula 1 in which B, U, V, W, R and R.sup.4 have the meanings stated in claim 1 (cf. for example European Patent 253,213). ##STR7##
The novel compounds of the general formula 1 can also be prepared by reacting the terminal acetylenes 9, by a transition metal (TM)-catalyzed coupling, with the halides 10, preferably with the bromides (X=Br), or the iodides (X=I) in the presence of a catalyst, eg. PdCl.sub.2, Pd(OAc).sub.2 or Pd(PPh.sub.3).sub.4, and of a base, such as triethylamine (cf. for example P. C. Vollhardt, Angew. Chem. 98 (1986), 268 and H. Yamanaka, Synthesis (1983), 312).
Scheme 5
A, B, R, U, V and W have the meanings stated in claim 1.
In an alternative procedure, the .alpha.-keto acid derivatives of the terminal acetylenes 11 can be converted with the halides 10 under transition metal ##STR8## (TM)-catalysis into the derivatives 5, and the latter can be converted as described above into the novel compounds of the formula 1. ##STR9##
In a further possible method for the preparation of the compounds of the general formula 1, the acetylene group in formula 12 is first produced by a known method (cf. for example Houben-Weyl, Vol. V/2a, page 33 et seq. (Viehe) or see Schemes 1+2) ##STR10## and the group Y is then converted into the group ##STR11##
Schemes 7-9 are intended to illustrate this. The ketocarboxylic esters 17 can be prepared starting from the o-bromobenzaldehydes 13. ##STR12##
The o-bromobenzaldehydes 12 can be reacted with the terminal acetylenes 3 under transition metal catalysis to give the aldehydes 14 (cf. W. B. Austin, J. Org. Chem. 46 (1981), 2280).
The cyanohydrins 15 are obtained from the aldehydes 14 by reaction with a metal cyanide, such as NaCN or KCN, in the presence of an acid, eg. hydrochloric acid (cf. for example Organikum, 16th Edition, page 445 (1986)).
The mandelic acid derivatives 16 can be prepared from the cyanohydrins 15 via a Pinner reaction (cf., for example, Org. Synth. Coll. 4(1963), 58).
Oxidation of the mandelic acid derivatives 16, for example with a chromium compound, such as chromium trioxide, with sodium hypochlorite or with TEMPO gives the .alpha.-ketoesters 17 (cf. for example Houben-Weyl, Vol. 4/1b, pages 425-464 (1975); TEMPO=tetramethylpiperidin-1-oxyl ).
The novel compounds of the formula 1a, in which A, U, V, W and R have the meanings stated in claim 1 and B is CO.sub.2 Me, can be prepared from the ketoesters 17 as shown in Schemes 3 and 4. The .alpha.-ketocarboxylic esters 17 can be synthesized starting from the halogen derivatives 18, by Grignard reaction with oxalic acid compounds 19 similarly to Scheme 8 (cf., for example, J. S. Nimitz, J. Org. Chem. 46 (1981), 211). ##STR13##
In a further possible method, carboxylic acids 20 are converted via the stage of the acyl chlorides into the cyanides 21 and the latter are converted into the ketoesters 17 by a Pinner reaction. ##STR14## (cf. for example Organikum, 16th Edition, 423 et seq. (1986) and Angew. Chem. 94 (1982), 1).
The novel compounds of the formula 1 where A, X, Y, Z and R have the meanings stated in claim 1 and B is hydroxyl or alkylamino can be prepared from the carboxylic ester derivatives 1a. ##STR15##
The carboxylic acids 22 are obtained by hydrolysis by known methods (cf. Organikum, 16th Edition, page 415 et seq. and page 622 (1986)).
They can be converted into the acyl chlorides 23 (cf. Organikum, 16th Edition, page 423 et seq. (1986)).
The amides 24 are either obtained from these in a conventional manner (Organikum, 16th Edition, page 412 (1986)) or alternatively from the carboxylic esters 1a directly by aminolysis with amines.
However, the novel compounds of the general formula I can also be prepared by converting a suitably substituted styryl compound 25 in a conventional manner into the corresponding acetylene derivative 1. ##STR16##
Where X is H and Y is halogen or X is halogen and Y is H, the reaction is carried out in the presence of a base, eg. sodium hydride, potassium hydroxide, Triton B or n-butyllithium (cf. for example H. Zimmer et al., Chimia 28 (1974), page 656 et seq.) (Triton B=2-benzyltrimethylammonium hydroxide).
Where X and Y are each halogen, the cleavage can be carried out with zinc (cf. for example H. G. Viehe, Chemistry of Acetylenes, Marcel Dekker, New York, 1969, page 134 et seq.).

The Examples which follow illustrate the preparation of the compounds.

The novel compounds are suitable as fungicides.
The fungicidal compounds according to the invention, or agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), dispersions, emulsions, oil dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.
Normally, the plants are sprayed or dusted with the active ingredients or the seeds of the plants are treated with the active ingredients.
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 as auxiliary solvents. Suitable auxiliaries for this purpose are solvents such as aromatics (e.g., xylene), chlorinated aromatics (e.g., chlorobenzenes), paraffins (e.g., crude oil fractions), alcohols (e.g., methanol, butanol), ketones (e.g., cyclohexanone), amines (e.g., ethanolamine, dimethylformamide), and water; carriers such as ground natural minerals (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.
Examples of surfactants are: alkali metal, alkaline earth metal and ammonium salts of aromatic sulfonic acids, e.g., ligninsulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl and alkylaryl sulfonates, and alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexadecanols, heptadecanols, and octadecanols, salts of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethyelene, octylphenol ethers, ethoxylated isooctylphenol, ethoxylated octylphenol and ethoxylated nonylphenol, alkylphenol polyglycol ethers, tributulphenyl polyglycol ethers, 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 methyl cellulose.
Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients with a solid carrier.
Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. Examples of solid carriers are mineral earths such as silicic acids, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain meals, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.

The novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the class consisting of the Ascomycetes and Basidiomycetes. Some of them have a remarkably high systemic mobility and action after application to the soil and particularly to foliage.
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 compounds are applied by treating the seeds, plants, materials or soil to be protected against fungus attack with a fungicidally effective amount of the active ingredients.
The compounds may be applied before or after infection of the materials, plants or seeds by the fungi.
The compounds I are particularly useful for controlling the following plant diseases:
Erysiphe graminis in cereals,
Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits,
Podosphaera leucotricha in apples,
Uncinula necator in vines,
Puccinia species in cereals,
Rhizoctonia solani in cotton,
Ustilago species in cereals and sugar cane,
Venturia inaequalis (scab) in apples,
Helminthosporium species in cereals,
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,
Phytophthora infestans in potatoes and tomatoes,
Fusarium and Verticillium species in various plants,
Plasmopara viticola in grapes,
Alternaria species in fruit and vegetables.
The novel compounds may also be used for protecting materials (timber), for example against Paecilomyces variotii.
The fungicidal agents generally contain from 0.1 to 95, and preferably from 0.5 to 90, wt % of active ingredient.
The application rates depend on the type of effect desired, but are generally from 0.02 to 3 kg of active ingredient per hectare. when the active ingredients are used for treating seed, application rates of from 0.001 to 50, and preferably from 0.01 to 10, g per kg of seed are generally required.
When the agents according to the invention are used as fungicides, they may be employed together with other active ingredients, e.g., herbicides, insecticides, growth regulators, other fungicides and fertilizers.
When admixed with other fungicides, the spectrum of fungicidal action is in many instances increased.
Use Examples
In the active ingredients used for comparison purposes, U, V and W=H, A=CH.sub.3 ON.dbd., B=CH.sub.3 O and R=phenyl (compound 1), R=2-chlorophenyl (compound B), and R=4-CF.sub.3 -phenyl (compound C). All of these compounds are known from EP 253 213.
Use Example 1
Action on cucumber mildew
Young cucumber plants of the "Chinesische Schlange" variety were sprayed to runoff at the two-leaf stage with an aqueous spray liquor. The next day these plants were sprayed with an aqueous conidial suspension of cucumber mildew (Erysiphe cichoracearum and Sphaerotheca fuliginea), and kept in the greenhouse at 20 to 22.degree. C. and a relative humidity of 70 to 80%. The extent of fungus spread was determined 21 days after application of the active ingredients.
The results show that the active ingredients from Table 2, no. 33 (2,33), 2,43; 2,148 and 2,166 have, when applied as a spray liquor containing 63 ppm of active ingredient, a better fungicidal action (10% leaf attack) than prior art comparative active ingredients A, B and C (45% leaf attack).
Use Example 2
Action on Botrytis cinerea in paprika pods (fruit test)
Slices of green paprika pods were sprayed to runoff with aqueous formulations containing 80% of active ingredient and 20% of emulsifier. Two hours after the sprayed-on layer had dried, the slices were inoculated with a spore suspension of Botrytis cinerea containing 1.7.times.10.sup.6 spores per ml of a 2% biomalt solution. The inoculated slices were then incubated in moist chambers for 4 days at 18.degree. C. The extent of Botrytis spread on the slices was then assessed visually.
The results show that active ingredients 2,25; 2,35; 2,166 and 2,179, when applied as spray liquors containing 500 ppm of active ingredient, have a better fungicidal action (10% attack) than prior art comparative active ingredient A (30% attack).

Leaves of potted vines of the Muller-Thurgau variety were sprayed with aqueous suspensions containing (dry basis) 80% of active ingredient and 20% of emulsifier. To assess the duration of action, the plants were set up, after the sprayed-on layer had dried, for 8 days in the greenhouse. Then the leaves were infected with a zoospore suspension of Plasmopara viticola. The plants were first placed for 48 hours in a water vapor-saturated chamber at 24.degree. C. and then in a greenhouse for 5 days at from 20.degree. to 30.degree. C. To accelerate and intensify the sporangiophore discharge, the plants were 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 1,195; 2,25; 2,35; 2,43; 2,86; 2,88; 2,92; 2,94; 2,95 and 2,148, when applied as spray liquors containing 16 ppm of active ingredient, have a better fungicidal action (5% leaf attack) than prior art comparative active ingredient C (35% leaf attack).
