This application claims priority under 35 U.S.C. §§ 119 and/or 365 to Patent Application No. 101 41 339.4 filed in Germany on Aug. 23, 2001 and Patent Application No. 102 17 697.3 filed in Germany on Apr. 20, 2002; the entire contents of which are hereby incorporated by reference.
The invention relates to the use of substituted aryl- and heteroarylpropargylamines as pesticides, in particular against harmful arthropods and helminths.
In EP-A-0 041 324, 1-[3-(3,5-bistrifluoromethylphenyl)-2-propynyl]-4-tert-butylpiperidine is described as rodenticide. Similar compounds in which the tertiary butyl radical is substituted are described in DE-A-3 504 412. Further compounds of this type in which the butyl radical is replaced by other alkyl radicals are described in 1987 BCPC mono. No. 37 Stored Products Pest Control, p. 125. In addition, there are further publications in which compounds are mentioned in which aryl radicals are attached via propargyl to nitrogen-containing heterocycles.
Surprisingly, it has now been found that compounds of this type have insecticidal, acaricidal and helminticidal action. Some of the compounds are novel.
The invention provides a method for controlling harmful arthropods, such as insects and Acarina, and helminths, such as parasites of animals and plant-damaging nematodes, which comprises applying to these pests or to the plants or animals, areas or substrates infected by them an effective amount of a compound of the formula (I)
where
The invention also provides the use of compounds of the formula (I) for controlling arthropods, such as insects and Acarina, and helminths, such as parasites of animals and plant-damaging nematodes.
Many of the compounds of the formula (I) are novel, and the invention embraces all novel compounds of the formula (I), in particular those in which
In the above formula, a hydrocarbon radical is a straight-chain, branched or cyclic saturated, partially saturated, unsaturated or aromatic organic radical having preferably 1 to 20 carbon atoms, for example alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl or benzyl. This definition also applies to composite terms, such as cycloalkylalkenyl, cycloalkynylalkyl and arylalkynyl. If a hydrocarbon radical contains additional heteroatoms, these can in principle, i.e. the chemical structure permitting, be located in any position of the hydrocarbon radical.
In formula (I) and all subsequent formulae, carbon-containing radicals in the form of a chain, such as alkyl, alkoxy, haloalkyl, haloalkoxy, alkylamino and alkylthio, and the corresponding radicals which are unsaturated and/or substituted in the carbon skeleton, such as alkenyl and alkynyl, can in each case be straight-chain or branched. Unless indicated otherwise, in these radicals the lower carbon skeletons, preferably those having 1 to 6 carbon atoms or, in the case of unsaturated groups, 2 to 4 carbon atoms, are preferred.
Alkyl radicals, also in composite groups such as alkoxy, haloalkyl, etc., are, for example, methyl, ethyl, n- or isopropyl, n-, iso-, t- or 2-butyl, pentyl radicals, hexyl radicals, such as n-hexyl, isohexyl and 1,3-dimethylbutyl, heptyl radicals, such as n-heptyl, 1-methylhexyl, 1,4-dimethylpentyl, and benzyl; alkenyl and alkynyl radicals, also in the composite groups, have the meaning of the unsaturated radicals which are possible and correspond to the alkyl radicals; alkenyl is, for example, allyl, 1-methylprop-2-en-1-yl, 2-methyl-prop-2-en-1-yl, but-2-en-1-yl, but-3-en-1-yl, 1-methyl-but-3-en-1-yl and 1-methyl-but-2-en-1-yl; alkynyl is, for example, propargyl, but-2-yn-1-yl, but-3-yn-1-yl, 1-methyl-but-3-yn-1-yl. The multiple bond can be located in any position of the unsaturated radical.
Cycloalkyl is a carbocyclic saturated ring system having preferably three to eight carbon atoms, for example cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. Analogously, cycloalkenyl is a monocyclic alkenyl group having three to eight carbon ring members, for example cyclopropenyl, cyclobutenyl, cyclopentenyl and cyclohexenyl, where the double bond can be located in any position.
In the case of composite radicals, such as cycloalkylalkenyl, the first-mentioned radical can be located in any position of the second-mentioned radical.
In the case of an amino group which is doubly substituted, such as dialkylamino, these two substituents can be identical or different.
Halogen is fluorine, chlorine, bromine or iodine. Haloalkyl, -alkenyl and -alkynyl, etc., is alkyl, alkenyl and alkynyl, respectively, which is partially or fully substituted by halogen, preferably by fluorine, chlorine and/or bromine, in particular by fluorine or chlorine, for example CF3, CHF2, CH2F, CF2CF3, CHClCH2F, CCl3, CCl2F, CClF2, CHCl2, CH2CH2Cl; haloalkoxy is, for example, OCF3, OCHF2, OCH2F, OCF2CF3, OCH2CF3 and OCH2CH2Cl; this applies correspondingly to other halogen-substituted radicals.
The term “heterocyclyl” is to be understood as meaning a saturated or partially unsaturated mono- or polycyclic ring system having preferably 3 to 14 ring members which contains one or more, preferably one to three, heteroatoms, preferably from a group consisting of oxygen, nitrogen (“N-heterocyclyl”) and sulfur. If chemically possible, the point of attachment can be in any position of the heterocycle.

Aryl is an aromatic mono- or polycyclic hydrocarbon radical having preferably 6 to 14, particularly preferably 6 to 12, carbon atoms, for example, phenyl, naphthyl, biphenyl and phenanthryl.
Heteroaryl is an aromatic mono-, bi- or tricyclic ring system having preferably 5 to 14 ring members which, in addition to carbon ring members, contains one to four nitrogen atoms or one to three nitrogen atoms (“N-heteroaryl”) and one oxygen or one sulfur atom or one oxygen or one sulfur atom. Examples of 5-membered heteroaryl are 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 1-pyrazolyl, 3-pyrazolyl, 4-pyrazolyl, 5-pyrazolyl, 1-imidazolyl, 2-imidazolyl, 4-imidazolyl, 1,2,4-triazol-3-yl, 1,3,4-triazol-2-yl, 1,2,3-triazol-1-yl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 3-isothiazolyl, 4-isothiazolyl, 5-isothiazolyl, 2-oxazolyl, 4-oxazolyl, 5-oxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 1-imidazolyl, 2-imidazolyl, 1,2,4-oxadiazol-3-yl, 1,2,4-oxadiazol-5-yl, 1,2,4-thiadiazol-3-yl, 1,2,4-thiadiazol-5-yl, 1,3,4-oxadiazol-2-yl, 1,3,4-thiadiazol-2-yl.

Depending on the nature and the attachment of the substituents, the compounds of the formula (I) can be present as stereoisomers. If, for example, one or more alkenyl groups are present, diastereomers may occur. If, for example, one or more asymmetrically substituted carbon atoms are present, enantiomers and diastereomers may occur. From the mixtures obtained in the preparation, stereoisomers can be obtained by customary separation methods, for example by chromatographic separation procedures. It is also possible to selectively prepare stereoisomers by using stereoselective reactions and employing optically active starting materials and/or auxiliaries. The invention also relates to all stereoisomers and mixtures thereof which are embraced by formula (I) but not specifically defined.
The term “partially or fully halogenated” is meant to express that in the groups thus characterized some or all of the hydrogen atoms may be replaced by identical or different halogen atoms as mentioned above.
If a group is polysubstituted, this is meant to be understood such that, when combining the different substituents, the general principles of the synthesis of chemical compounds are observed, i.e. that the formation of compounds is avoided of which the person skilled in the art knows that they are chemically unstable or impossible.
The symbols and indices of the formula (I) are preferably as defined below:

alkyl-NH—NH—CO— and arylalkyl-NH—NH—CO—.
Particularly preferably, R2 and R3 together with the nitrogen atom to which they are attached form N-heteroaryl or N-heterocyclyl, unsubstituted or mono- or polysubstituted by identical or different substitutents from the group consisting of (C1–C4)-alkyl, (C2–C4)-alkenyl, (C2–C4)-alkynyl, (C3–C6)-cycloalkyl, (C3–C6)-heterocyclyl, (C3–C8)-cycloalkenyl, (C3–C6)-cycloalkyl-(C1–C4)-alkyl, aryl-(C1–C4)-alkyl, heteroaryl-(C1–C4)-alkyl, (C1–C4)-alkylcarbonyl, (C1–C4)-alkylcarbonyloxy, (C1–C4)-alkylsulfonyl, (C1–C4)-alkylsulfonyloxy, (C1–C4)-alkoxycarbonyl, SCN, (C1–C4)-dialkylamino, formyl—where the groups mentioned are unsubstituted or substituted by one or more identical or different radicals from the group consisting of halogen, nitro, cyano, alkyl, haloalkyl, cycloalkyl, alkenyl, alkynyl, phenyl, alkoxy, haloalkoxy and alkylthio. Two substituents together may form a group —O—CH2—O— or —O—(CH2)2—O— or, at the same carbon atom, ═O.
Very particularly preferably, R2 and R3 together with the nitrogen atom to which they are attached form N-heteroaryl or N-heterocyclyl, unsubstituted or mono- or polysubstituted by identical or different substituents from the group consisting of (C1–C4)-alkyl, (C2–C4)-alkenyl, (C2–C4)-alkynyl, (C3–C6)-cycloalkyl, (C3–C6)-heterocyclyl, (C3–C8)-cycloalkenyl, (C3–C6)-cycloalkyl-(C1–C4)-alkyl, aryl-(C1–C4)-alkyl, heteroaryl-(C1–C4)-alkyl, (C1–C4)-alkylcarbonyl, (C1–C4)-alkylcarbonyloxy, (C1–C4)-alkoxycarbonyl, (C1–C4)-alkylsulfonyl, (C1–C4)-alkylsulfonyloxy—where the groups mentioned are unsubstituted or substituted by one or more identical or different radicals from the group consisting of halogen, nitro, cyano, alkyl, haloalkyl, cycloalkyl, alkenyl, alkynyl, alkoxy, haloalkoxy and alkylthio —SCN, (C1–C4)-dialkylamino, formyl, ═O, —O—CH2—O—, —O—(CH2)2—O—.
Preferably, R2 and R3 together with the nitrogen atom to which they are attached form a 6-azabicyclo[3.2.1]octane, 1,2,5,6-tetrahydropyridine, decahydroquinoline, azepam, morpholine, piperazine, piperidine, unsubstituted or mono- or polysubstituted by identical or different substituents mentioned above, particularly preferably a piperidine.
Depending on the nature of the substituents defined above, the compounds of the formula (I) have acidic or basic properties and are able to form salts. Here, preference is given to the salts which are tolerable and customary in the field of pest control. If, for example, the compounds of the formula (I) carry groups such as hydroxyl, carboxyl or other groups which induce acidic properties, these compounds can be reacted with bases to give salts. Suitable bases are, for example, hydroxides, carbonates, bicarbonates of the alkali metals and alkaline earth metals, in particular those of sodium, potassium, magnesium and calcium, furthermore those of ammonia, of primary, secondary and tertiary amines having (C1–C4)-alkyl radicals and of mono-, di- and trialkanolamines of (C1–C4)-alkanols. If, for example, the compounds of the formula (I) carry groups such as amino, alkylamino and other groups which induce basic properties, these compounds can be reacted with acids to give salts. Suitable acids are, for example, mineral acids, such as hydrochloric acid, sulfuric acid and phosphoric acid, organic acids, such as acetic acid or oxalic acid, and acidic salts, such as NaHSO4 and KHSO4. The salts obtainable in this manner have insectidical, acaricidal and/or helminthicidal/nematicidal properties, too.
The compounds of the formula (I) may have one or more asymmetrically substituted carbon atoms or stereoisomers on double bonds. Accordingly, enantiomers or diastereomers may occur. The invention embraces both the pure isomers and their mixtures. The mixtures of diastereomers can be separated into the isomers by customary methods, for example by selective crystallization from suitable solvents or by chromatography. Racemates can be separated by customary methods into the enantiomers.
The compounds according to the invention are prepared by methods known per se from the literature, as described in standard works on organic synthesis, for example Houben-Weyl, Methoden der Organischen Chemie [Methods of organic chemistry], Georg-Thieme-Verlag, Stuttgart.
The preparation is carried out under reaction conditions which are suitable and known for the reactions mentioned. It is also possible to employ variants known per se which are not mentioned in more detail here.
If desired, the starting materials can also be formed in situ, such that they are not isolated from the reaction mixture but immediately converted further into the compounds of the formula (I).
In all of the formulae mentioned below, the substituents and symbols have the same meaning as described under formula (I) unless defined otherwise.
Depending on the meaning of the substituents, the compounds of the formula (I) can be prepared, for example, by one or more of the processes shown in the schemes below.
The palladium-catalyzed crosscoupling (Sonogashira coupling) shown in scheme 1 of a compound of the formula (II) in which X is —OSO2CF3 or halogen, preferably iodine, with a compound of the formula (III) gives the compounds of the formula (I) according to the invention. This reaction is preferably carried out in the presence of an amine base, for example diethylamine, triethylamine, piperidine, pyrrolidine or DBU, which, in addition to other solvents such as benzene, toluene, DMF, THF or diethyl ether, may also serve as solvent, or in the presence of another suitable base, for example an alkali metal alkoxide, such as potassium tert-butoxide in an inert organic solvent, such as DMSO, acetonitrile; and in the presence of a solvent and a palladium catalyst and also a copper(I) salt (Y is preferably I, Cl, Br, cyano or SCN), preferably copper(I) iodide (Y=I). Suitable palladium catalyst systems are, for example, Pd(PPh3)4, PdCl2(PPh3)2 and Pd(OAc)2(PPh3)2 or Pd(OAc)2 and a triarylphosphine, preferably triphenylphosphine or tri-(o-tolyl)phosphine. These methods are described, for example, in Tetrahedron Lett. 4467 (1975), Comprehensive Organic Synthesis (B. M. Trost, I. Flemming, Eds), Pergamon Press, Oxford, Vol 3, 521–549 (1991), Org. Prep. Proct. Int. 129 (1995), J. Med. Chem. 40, 3542 (1997), J. Org. Chem. 63, 1109 (1998).
Compounds of the formula (II) are either commercially available or can be prepared according to generally known methods, for example Houben-Weyl, Methoden der Organischen Chemie, Georg-Thieme-Verlag, Stuttgart or Chem. Pharm. Bull. 27, 270 (1979).
Compounds of the formula (III) can be prepared, for example, according to scheme 2 from compounds of the formula (IV), in which X′ is a leaving group, for example a chlorine, bromine or iodine atom or an alkylsulfonyloxy or arylsulfonyloxy radical, for example a tosyloxy radical.
The compounds of the formula (III) are obtained in the presence of an inorganic or organic base, such as potassium carbonate or excess amine of the formula (V), in an inert organic solvent, such as methanol, acetone or DMF. Such methods are known, for example, from Org. Magn. Reson. 14, 161 (1980), Tetrahedron 41, 5685 (1985), J. Med. Chem. 34, 746 (1991), J. Org. Chem. 56, 3707 (1991), J. Org. Chem. 57, 3000 (1992), J. Med. Chem. 37, 2735 (1994).
Compounds of the formula (I) in which A is CR4R5, where R5 is hydrogen, in particular those in which A is CH2, are also obtainable, for example, according to scheme 3.
Compounds of the formula (I) are obtained according to scheme 3 by reacting compounds of the formula (V) with compounds of the formula (VI) and an aldehyde, such as, for example, benzaldehyde, acetaldehyde or formaldehyde, or an aldehyde source, such as paraformaldehyde or formalin, in the presence of a copper(I) salt, preferably copper(I) chloride (Y=Cl), in an inert organic solvent, such as, for example, dioxan. Such methods are known, for example, from Chem. Ber. 66, 418 (1933), J. Prakt. Chem. 331, 187 (1989), Tetrahedron Lett. 39, 967 (1998).
Compounds of the formula (VI) are either commercially available, or they can be obtained by Sonogashira coupling and subsequent removal of the protective group from R1 X and a protected acetylene equivalent, such as, for example, trimethylsilylacetylene or 2-methylbut-3-yn-2-ol, according to known methods. Such methods are described, for example, in Comprehensive Organic Synthesis (B. M. Trost, I. Flemming, Eds), Pergamon Press, Oxford, Vol 3, 521–549 (1991), Synthesis. (1980), 627, J. Org. Chem. 50, 1763 (1985), Tetrahedron Lett. 34, 2071 (1993), Angew. Chem. Int. Ed. Engl. 18, 406 (1993), Synthesis (1996), 589.
In particular compounds of the formula (I), in which A is CR4R5 can also be obtained, for example, according to scheme 4.
According to scheme 4, the compounds of the formula (I) are obtained by reacting compounds of the formula (VII) in which Z is a chlorine, bromine or iodine atom or an alkylsulfonyloxy or arylsulfonyloxy radical, for example a tosyloxy radical, with compounds of the formula (VIII), in which M is an alkali metal atom, preferably a lithium atom. If Z in the formula (VII) is chlorine, bromine or iodine, M in the formula (VIII) may furthermore be a hydrogen atom. If M in the formula (VIII) is a hydrogen atom, the reaction is carried out in the presence of an inorganic base, such as potassium carbonate, and in an inert organic solvent, such as acetone or DMF. If M in the formula (VIII) is not hydrogen, preference is given to inert organic solvents, such as diethyl ether or THF.
Compounds of the formula (VII) can be prepared by or analogously to known methods. These methods are known, for example, from Chem. Phys. Lipids 13, 159 (1974), Synthesis (1975), 255, J. Am. Chem. Soc. 60, 2662 (1938), Bull. Chem. Soc. Jpn. 46, 954 (1973), J. Med. Chem. 21, 253 (1978), Bull. Soc. Chim. Fr. (1969), 4514, J. Org. Chem. 49, 4344 (1984), J. Med. Chem. 41, 1084 (1998), J. Org. Chem. 63, 7472 (1998).
Collections of compounds of the formula (I) which can be synthesized by the abovementioned schemes may also be prepared in a parallel manner and this may be effected manually or in a semiautomated or fully automated manner. In this case, it is possible, for example, to automate the procedure of the reaction, the work-up or the purification of the products or of the intermediates. In total, this is to be understood as meaning a procedure as is described, for example, by S. H. DeWitt in “Annual Reports in Combinatorial Chemistry and Molecular Diversity: Automated Synthesis”, Volume 1, Verlag Escom 1997, pages 69 to 77.
A number of commercially available apparatuses as are offered by, for example, Stem Corporation, Woodrolfe Road, Tollesbury, Essex, CM9 8SE, England or H+P Labortechnik GmbH, Bruckmannring 28, 85764 Oberschleiβheim, Germany or Radleys, Shirehill, Saffron Walden, Essex, England may be used for the parallel procedure of the reaction and work-up. For the parallel purification of compounds of the formula (I), or of intermediates obtained during the preparation, use may be made, inter alia, of chromatography apparatuses, for example those from ISCO, Inc., 4700 Superior Street, Lincoln, Nebr. 68504, USA.
The apparatuses mentioned lead to a modular procedure in which the individual process steps are automated, but manual operations have to be performed between the process steps. This can be avoided by employing semiintegrated or fully integrated automation systems where the automation modules in question are operated by, for example, robots. Such automation systems can be obtained, for example, from Zymark Corporation, Zymark Center, Hopkinton, Mass. 01748, USA.
In addition to the method described here, compounds of the formula (I) may be prepared in part or fully by solid-phase-supported methods. For this purpose, individual intermediate steps or all intermediate steps of the synthesis or of a synthesis adapted to suit the procedure in question are bound to a synthetic resin. Solid-phase-supported synthesis methods are described extensively in the specialist literature, for example Barry A. Bunin in “The Combinatorial Index”, Verlag Academic Press, 1998.
The use of solid-phase-supported synthesis methods permits a series of protocols which are known from the literature and which, in turn, can be performed manually or in an automated manner. For example, the “tea-bag method” (Houghten, U.S. Pat. No. 4,631,211; Houghten et al., Proc. Natl. Acad. Sci, 1985, 82, 5131–5135), in which products from IRORI, 11149 North Torrey Pines Road, La Jolla, Calif. 92037, USA, are employed, may be semiautomated. The automation of solid-phase-supported parallel syntheses is performed successfully, for example, by apparatuses from Argonaut Technologies, Inc., 887 Industrial Road, San Carlos, Calif. 94070, USA or MultiSynTech GmbH, Wullener Feld 4, 58454 Witten, Germany.
The preparation according to the processes described herein yields compounds of the formula (I) in the form of substance collections which are referred to as libraries. The present invention also relates to libraries which comprise at least two compounds of the formula (I).
The compounds of the formula (I) are suitable for controlling animal pests, in particular arthropods such as insects, Acarina and helminths, such as parasites of animals and plant-damaging nematodes, very especially preferably for controlling insects and arachnids, which are encountered in agriculture, in animal husbandry, in livestock breeding, in horticulture, in forests, in the protection of stored goods and materials and in the domestic sector and in the hygiene sector, and have good plant tolerance and favorable toxicity to warm-blooded species. They are active against normally sensitive and resistant species and against all or individual development stages. The above mentioned pests include:
The compounds of the formula (I) are also suitable for controlling animal pests, in particular arthropods, such as insects and Acarina, in rooms, specifically for controlling flies, such as, for example, from the family Muscidae (for example common house-flies, domestic flies), Calliphoridae (for example greenbottles, “death flies” (Cynomyia mortuorum), bluebottles) and Sarcophagidae (for example flesh-flies), mosquitoes, such as, for example, Aedes aegypti, Anopheles arabiensis and Culex quinquefasciatus, and cockroaches, such as, for example Blattella germanica and Periplaneta americana.
The invention relates to compositions, for example pesticidal compositions, preferably insecticidal, acaricidal, ixodicidal, or helminthicidal/nematicidal, particularly preferably insecticidal, acaricidal and helminthicidal/nematicidal compositions which comprise one or more compounds of the formula (I) in addition to suitable formulation auxiliaries.
In general, the compositions according to the invention comprise from 1 to 95% by weight of the active compounds of the formula (I).
For preparing the compositions according to the invention, the active compound and the other additives are combined and formulated as a suitable use form.
They can be formulated in various ways, depending on how this is predetermined by the biological and/or chemico-physical parameters. Suitable formulation possibilities are therefore:
Wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions, sprayable solutions, oil- or water-based dispersions (SC), suspoemulsions (SE), dusting powders (DP), seed dressings, granules in the form of microgranules, sprayed granules, absorption granules and adsorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits. In addition, the compositions can be employed as dips or mist applications, in the form of foams, pastes, gels, ointments, lotions, shampoos, hair-setting compositions, active-compound-containing mats (for example flat or in the form of a cushion), impregnated articles, aerosols, pressurized and non-pressurized sprays, additives to color lacques and foodstuff, and also for use as fumigants and evaporator compositions, as combustible solids (for example in the form of a cone or coil) or as combustible oils (distributed, for example, via a heated wick) and in further formulations familiar to the person skilled in the art.
These individual types of formulation are known in principle and are described, for example, in: Winnacker-Küchler, “Chemische Technologie” [Chemical Technology], Volume 7, C. Hanser Verlag Munich, 4th Edition 1986; van Falkenberg, “Pesticides Formulations”, Marcel Dekker N.Y., 2nd Edition 1972–73; K. Martens, “Spray Drying Handbook”, 3rd Edition 1979, G. Goodwin Ltd. London.
The necessary formulation auxiliaries, i.e. carrier and/or surface-active substances such as inert materials, surfactants, solvents and further additives, are likewise known and are described, for example, in: Watkins, “Handbook of Insecticide Dust Diluents and Carriers”, 2nd Edition, Darland Books, Caldwell N.J.; H. v. Olphen, “Introduction to Clay Colloid Chemistry”, 2nd Edition, J. Wiley –Sons, N.Y.; Marsden, “Solvents Guide”, 2nd Edition, Interscience, N.Y. 1950; McCutcheon's, “Detergents and Emulsifiers Annual”, MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, “Encyclopedia of Surface Active Agents”, Chem. Publ. Co. Inc., N.Y. 1964; Schönfeldt, “Grenzflächenaktive Äthylenoxidaddukte” [Surface-active ethylene oxide adducts], Wiss. Verlagsgesell., Stuttgart 1967; Winnacker-Küchler, “Chemische Technologie” [Chemical Technology], Volume 7, C. Hanser Verlag Munich, 4th Edition 1986.
Combinations with other substances having a pesticidal action, fertilizers and/or growth regulators can be prepared on the basis of these formulations, for example in the form of a ready-to-use formulation or as a tank mix. Wettable powders are preparations which are uniformly dispersible in water and which, alongside the active compound, and in addition to a diluent or inert substance, also comprise wetting agents, for example polyethoxylated alkylphenols, polyethoxylated fatty alcohols or alkyl- or alkylphenolsulfonates, and dispersing agents, for example sodium lignosulfonate or sodium 2,2′-dinaphthylmethane-6,6′-disulfonate.
Emulsifiable concentrates are prepared by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or also higher-boiling aromatics or hydrocarbons, with the addition of one or more emulsifiers. Emulsifiers which can be used are, for example: calcium alkylaryl-sulfonates, such as Ca dodecylbenzenesulfonate, or nonionic emulsifiers, such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters.
Dusting powders are obtained by, for example, grinding the active compound with finely divided solid substances, for example talc, naturally occurring clays, such as kaolin, bentonite and pyrophyllite, or diatomaceous earth. Granules can be prepared either by spraying the active compound onto granular inert material capable of adsorption or by applying active compound concentrates to the surface of carrier substances, such as sand, kaolinites or granular inert material, by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or mineral oils. Suitable active compounds can also be granulated in the manner customary for the preparation of fertilizer granules—if desired as a mixture with fertilizers.
Aerosols, sold, for example, in cans, are prepared by dissolving the active compound in water and/or organic solvents, such as, for example, acetone, deodorized petroleum, saturated C8–C13-hydrocarbons, vegetable oils, with addition of further suitable substances, such as, for example, emulsifiers, piperonyl butoxide, sorbitan monooleate, polyoxyethylene glycerol monooleate, fragrances and suitable propellents, such as, for example, carbon dioxide or butane. Ready-to-use sprays, for example for use in rooms, are obtained, for example, by mixing the active compound with odorless kerosine and antioxidants, it being possible to admix further additives, such as, for example, emulsifiers, synergists (for example piperonyl butoxide) or fragrances. Baits can be prepared, for example, by mixing the active compound with attractants and/or foodstuffs, such as, for example, sugar, and also carrier materials, such as, for example, paraffin wax.
A further advantageous embodiment for use in rooms is the use as a fumigant and an evaporator composition, which can be employed by various methods. In one of these methods, combustible solids, such as, for example, sawdust (for example pine sawdust), starch and coconut shell powder and also powdered leaves and stalks of further plants (for example pyrethrum, cedar) are, with addition of colorants and, if appropriate, fungicides, solidifed in specific forms, such as, for example, a meander, a coil or a cone, using suitable binders, and the active compound is then applied. The active compound is then distributed in the room by slow and controlled burning. In another method, mats or cushions of non-combustible fibers are used as carriers into which the active compound and, if appropriate, further substances are incorporated. These carriers are placed onto a heating plate which is heated under controlled conditions, thus releasing the active compound. In a further method, an oil is used to which the active compound is added and into which a wick consisting, for example, of cotton and/or cellulose in compressed form, is dipped, which wick releases the active compound from the oil into the room on burning. In a variant of this method, a wick of non-combustible fibers is used which is heated by an electric device, thus effecting the distribution of the active compound contained in the oil throughout the room. In the above-mentioned methods, the active compound is applied either directly or in already formulated form. Frequently, for example, colorants and fragrances are added, and also suitable fungicides for protecting the carriers made of natural products against natural decomposition.
In wettable powders, the active compound concentration is usually about 10 to 90% by weight, the remainder to make up 100% by weight comprising customary formulation constituents. In emulsifiable concentrates, the active compound concentration can be about 5 to 80% by weight. Dust-like formulations usually comprise 5 to 20% by weight of active compound, and sprayable solutions about 2 to 20% by weight. In granules, the content of active compound partly depends on whether the active compound is present in liquid or solid form and what granulating auxiliaries, fillers and the like are used. Baits generally comprise from 0.01 to 60% by weight of active compound, preferably from 0.1 to 5% by weight; aerosols generally comprise from 0.01 to 50% by weight, preferably from 0.1 to 5% by weight; ready-to-use sprays generally comprise from 0.01 to 50% by weight, preferably from 0.05 to 10% by weight. The active compound contents in fumigants and evaporator compositions are, in the case of combustible solids, generally in the range from 0.01 to 60% by weight, in the case of active-compound-comprising mats and cushions in the range from 0.01 to 60% by weight and in the case of active-compound-comprising oils in the range from 0.01 to 90% by weight.
In addition, the active compound formulations mentioned comprise, if appropriate, the particular customary tackifiers, wetting agents, dispersing agents, emulsifiers, penetration agents, solvents, fillers or carrier substances.
For use, the concentrates in the commercially available form are diluted in the customary manner, if appropriate, for example by means of water in the case of wettable powders, emulsifiable concentrates, dispersions and in some cases also microgranules. Dust-like and granular formulations as well as sprayable solutions are usually not diluted further with additional inert substances before use.
The required amount applied varies with the external conditions, such as temperature or humidity. It can vary within wide limits, for example between 0.0005 and 10.0 kg/ha or more of active substance, but is preferably between 0.001 and 5 kg/ha.
The active compounds according to the invention can be present in their commercially available formulations and in the use forms prepared from these formulations in mixtures with other active compounds, for example pesticides such as insecticides, attractants, sterilizing agents, acaricides, nematicides, fungicides, molluscides, growth-regulating substances or herbicides.
The pesticides include, for example, phosphoric acid esters, carbamates, carboxylic acid esters, formamidines, tin compounds and substances produced by microorganisms.
Preferred partners for the mixtures are:
The abovementioned components are known active substances, many of which are described in C D S Tomlin (Editor), The Pesticide Manual, 12th edition, The British Crop Protection Council, Farnham, UK, 2000.
The active compound content of the use forms prepared from the commercially available formulations can be from 0.00000001 to 95% by weight of active compound, preferably between 0.00001 and 1% by weight. The active compounds are used in a customary manner appropriate for the use forms.
The compounds of the formula (I) can be employed in their commercially available formulations, also in combination with fungicides. These fungicides are generally active compounds which are described in C D S Tomlin (Editor), The Pesticide Manual, 12th edition, The British Crop Protection Council, Farnham, UK, 2000. Appiication is carried out in a customary manner adapted to suit the use forms, for example in the control of pathogenic fungi by applying a fungicidally effective amount of a compound according to the invention or a composition according to the invention to these fungi or to the plants, areas or substrates infected with them, or to seed.
The compounds of the formula (I) can also be employed for controlling harmful organisms in crops of known or yet to be developed genetically engineered plants. As a rule, the transgenic plants are distinguished by particular advantageous properties, for example by resistances to certain crop protection agents, resistances to plant diseases or pathogens of plant diseases such as certain insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the harvested material with regard to quantity, quality, storage properties, composition and specific constituents. Thus, transgenic plants with an elevated starch content or altered starch quality, or those with a different fatty acid spectrum of the harvested material, are known.
The use in economically important transgenic crops of useful plants and ornamentals, for example, cereals such as wheat, barley, rye, oats, millet, rice, manioc and corn or else crops of sugar beet, cotton, soya, oilseed rape, potatoes, tomatoes, peas and other types of vegetables is preferred.
When being used in transgenic crops, in particular those in which the plants express an insecticide, effects are frequently found (in addition to the pesticidal effects which can be observed in other crops) which are specific to application in the transgenic crop in question, for example an altered or specifically widened spectrum of pests which can be controlled, or altered application rates which can be used for application.
The compounds of the formula (I) according to the invention or the compositions comprising them are used, for example, in agriculture, in horticulture, in forests and in the protection of materials and food. They are preferably used in economically important crops of useful plants and ornamentals, for example of cereals, such as wheat, barley, rye, oats, millet, rice, manioc and corn, or else crops of sugar beet, cotton, soya, oilseed rape, potatoes, tomatoes, peas and other types of vegetables.
The use of the compounds according to the invention embraces, in addition to direct application onto the harmful organisms, any other application in which compounds of the formula (I) act on the harmful organisms. Such indirect applications can, for example, be the use of compounds which, for example in the soil, the plant or the harmful organism, decompose into compounds of the formula (I) or are degraded into compounds of the formula (I).
The use according to the invention of compounds of the formula (I) or compositions comprising them, for example as insecticide, acaricide or helminthicide/nematicide, also includes the case where the compound of the formula (I) or its salt is formed from a precursor only after application, for example in the harmful organism, in a plant or in the soil.
In addition to the above mentioned and customary application methods, the active compounds of the formula (I) according to the invention have excellent systemic action. Accordingly, the active compounds can also be introduced into the plants via parts of the plant, both below ground and above ground (for example root, stolons, stem, trunk, leaf), if the active compounds are applied, in liquid or solid form, on or into the plant or into the direct vicinity of the plant (for example granules in soil application, application in flooded rice paddies, trunk injection in the case of trees, stem bandages in the case of perennial plants).
In addition, the active compounds according to the invention are particularly suitable for the treatment of vegetative and generative plant propagation material, such as, for example, of seeds, for example of cereals, vegetables, cotton, rice, sugar beet and other crops and ornamental plants, of bulbs, seedlings and tubers of other crops and ornamental plants which are propagated vegetatively. The treatment can be carried out before sowing or before planting (for example by special seed coating techniques, by dressing in liquid or solid form or as a seed-box treatment), during sowing or planting or after sowing or planting by special application techniques (for example furrow treatment). The amount of active compound used can vary within a relatively large range, depending on the application. In general, the application rates are between 1 g and 10 kg of active compound per hectare of soil surface. The treatment methods for plant propagation material and the plant propagation material treated in this manner are also provided by the invention.
The active compounds according to the invention are also suitable for use in the veterinary field, preferably for controlling endoparasites and ectoparasites, and in the field of animal husbandry. The active compounds according to the invention can be applied in a known manner, such as by oral administration in the form of, for example, tablets, capsules, drinks or granules, by dermal application in the form of, for example, dipping, spraying, pouring on and spotting on, and dusting, and by parenteral administration in the form of, for example, an injection.
Accordingly, the compounds of the formula (I) according to the invention can also be employed particularly advantageously in livestock keeping (for example cattle, sheep, pigs and poultry such as chicken, geese and the like). In a preferred embodiment of the invention, the compounds, if appropriate in suitable formulations, are administered orally to the animals, if appropriate together with the drinking water or feed. Since excretion in the feces is efficient, the development of insects in the animals' feces can be prevented very easily in this manner. The dosages and formulations which are suitable in each case depend, in particular on the species and the developmental stage of the productive livestock and also on the risk of infestation and can be established and determined readily by customary methods. In cattle the compounds can be employed at dosages of, for example, from 0.01 to 1 mg/kg of body weight.
In addition, the compounds according to the invention are also suitable for use in technical fields, for example as wood preservatives, as preservatives in paints, in cooling lubricants for metal working, or as preservatives in drilling and cutting oils.
Further preferred areas of use are the protection of stored products and materials, the hygiene sector and the domestic sector where, in a preferred embodiment of the invention, the composition according to the invention is used in the buildings in question and, if appropriate, combined with further measures, such as, for example, sticky boards or traps. Here, too, suitable dosages and formulations depend in particular on the type and the intensity of the risk of infestation and can be established and determined readily by customary methods.
The invention is illustrated by the examples below. The Preparation Examples may also comprise prior-art compounds which serve to illustrate the preparation process for the compounds according to the invention. Prior-art compounds, listed in the tables below in addition to compounds according to the invention, are also used in the process according to the invention.
A mixture of 2-iodotoluene (6.54 g), N-(2-propynyl)piperidine (3.69 g), dichlorobis(triphenylphosphino)palladium(II) (0.05 g) and copper(I) iodide (0.1 g) in dry diethylamine (50 ml) was heated under reflux for 5 hours. The solvent was removed under reduced pressure and the residue was taken up in diethyl ether and washed with water. The organic phase was dried over magnesium sulfate and concentrated completely under reduced pressure. Distillation of the residue under reduced pressure gave 3.98 g of an oil of boiling point 96–98° C./0.08 mm Hg.
Preparation of the starting material 1-(2-propynyl)piperidine:
With stirring, a solution of 2-propynyl chloride (40.31 g) in dry methanol (50 ml) was added dropwise to a solution of piperidine (92.14 g) in dry methanol (100 ml). The mixture was stirred at 25° C. for 3 hours and then filtered. The filtrate was concentrated under reduced pressure and the residue was distilled (boiling point: 163–165° C./atmospheric pressure).
When 2-iodotoluene was replaced by 4-iodoanisole, the process of Example 1 gave a crude product to which excess hydrochloric acid in methanol was added. Removal of the solvent gave, after crystallization from isopropanol, colorless needles of melting point 223–225° C.
The product from Example 2 was dissolved in water and the solution was made alkaline using 2N aqueous sodium hydroxide solution and extracted with diethyl ether. The ether extracts were dried using magnesium sulfate, and the solvent was then removed and the residue was distilled under reduced pressure. This gave an oil of boiling point 126–128° C./0.1 mm Hg.
A mixture of 3-fluoroiodobenzene (8.88 g), 4-methyl-1-(2-propynyl)piperidine (6.80 g), palladium acetate (0.045 g), tri-o-toloylphosphine (0.24 g) and copper(I) iodide (0.1 g) in dry diethylamine (50 ml) was heated under reflux for 5 hours. The solvent was removed under reduced pressure and the residue was taken up in diethyl ether and washed with water. The organic phase was dried over magnesium sulfate and the solvent was removed under reduced pressure. Distillation of the residue under reduced pressure gave an oil (5.20 g) of boiling point 105° C./0.07 mm Hg.
Preparation of the starting material 4-methyl-1-(2-propynyl)piperidine: At 0–5° C., propargyl bromide (12.01 g) was added dropwise with stirring to a suspension of 4-methylpiperidine (10.0 g) and potassium carbonate (13.96 g) in dry acetone (80 ml). The mixture was stirred at 50° C. for 6 hours and then filtered. The filtrate was concentrated under reduced pressure and the residue was taken up in dichloromethane. The organic phase was washed with water (3×15 ml), dried with sodium sulfate and concentrated under reduced pressure. Distillation of the residue under reduced pressure gave 12.73 g of an oil of boiling point 60° C./16 mm Hg.
With stirring, a solution of phenylacetylene (10.2 g) in dioxane (10 ml), a solution of piperidine (13.3 g) in dioxane (10 ml) and copper(I) chloride (0.1 g) were added successively to a suspension of paraformaldehyde (3.6 g) in dioxane (10 ml). The mixture was heated under reflux for 6 hours, allowed to cool to 25° C. and acidified using 20% strength hydrochloric acid. The solution was washed with diethyl ether and the aqueous phase was made alkaline using 50% strength aqueous sodium hydroxide solution and extracted with diethyl ether (3×100 ml). The organic phase was dried with magnesium sulfate and concentrated completely. Distillation of the residue under reduced pressure gave an oil (13.0 g) of boiling point 95° C./0.045 mm Hg.
A mixture of 1-(3,5-bistrifluoromethylphenyl)-3-bromoprop-1-yne (2.53 g), piperidine (5 ml) and anhydrous potassium carbonate (5 g) in dry acetone (50 ml) was heated at reflux with stirring for 18 h. Removal of the solvent under reduced pressure and distillation of the residue under reduced pressure gave 2.26 g of an oil of boiling point 95° C./0.025 mm Hg.
An excess of dry HCl gas was passed through a solution of 1-(3,5-bistrifluoromethylphenyl)-3-piperidinoprop-1-yne (2.26 g) in dry diethyl ether (200 ml). Filtration, washing (diethyl ether) and drying of the resulting white precipitate gave 2.16 g of a fine white powder of melting point 214.5° C.

Test 1
Disks of beet leaves (diameter 49 mm) were placed onto 20% agar in Petri dishes made of plastic (diameter 9 cm). Each dish was populated with 10 adults of Phaedon cochleariae which were cultivated on beets. The compound to be examined was prepared in an aqueous, 50% by volume strength acetone solution. The solution of the compound was then sprayed onto the infected leaf disks using a Potter tower, at an application rate of 660 liters per hectare. Each experiment was carried out with 4 repetitions. In the controls, the infected leaf disks were only sprayed with the 50% strength aqueous acetone solution, if at all.
After 48 h, the mortality was determined and, using Abbott's formula, compared to the mortality of the controls. The LD90 concentration (dosage which leads to 90% mortality, here stated in % by weight) as then calculated. The compounds of Examples 14, 18, 29, 33, 152, 1001 and 1039 showed an LD90 at a dosage of 0.05% or less.

Test 4
The compound to be examined was dissolved in pure acetone and mixed into soil having a moisture of about 10%. The solvent was evaporated, and in each case 5 g of treated soil were then filled into a tube, and 0.5 ml of water was added. 10 Gryllus bimaculatus nymphs (1st development stage) and a disk of green cabbage as a source of food were placed into each tube. Each experiment was carried out with 4 repetitions. The controls were untreated soil and soil which had been treated only with acetone. The ventilated tubes were cultivated at 25° C. for 48 h, after which the mortality was determined.

After 24 h, about 10 Lucilia sericata larvae of the 1st development stage were placed on the treated diet. Each experiment was carried out with 3 repetitions. The diet in the tubes of the control was treated only with an equivalent amount of acetone. The ‘minimum effective dose’ (MED) was defined as the lowest dosage at which the further development of the larvae is stopped, and as a consequence, there is no subsequent hatching of adult flies.
The compounds of Example 4 and 1039 showed an MED at 100 μg/glass or less.
Test 6

In 50% of the female Aedes aegypti, the compounds of Example 70 and 1036 caused a knockdown (syn. KT50; ‘knockdown time of 50% of individuals’, i.e. the time after which 50% of the mosquitoes were immobilized) after 12 and 11.5 minutes, respectively. For Culex quinquefasciatus, the KT50 was 8 and 9.25 minutes.
